I bought the Garmin nuvi 350 from Target and liked it, for a few hours.

But when the battery ran low, I plugged in the usb automotive charger I
keep in the car but I couldn't get the nuvi 350 to work anymore. So I
returned the defective unit and Target didn't charge the restocking fee
because it was defective.

I bought another Garmin nuvi 350 from Target and guess what. It too was
defective. It too wouldn't work when plugged into power! Maybe Target has a
bad batch of Garmins???????

Is this a common experience that two Garmin nuvi 350s in a row would not
work when plugged in? Should I try a third Garmin or just give up? I am
positive the charger is working because I use it every day for my cell
phone! So it must be something wrong with Garmin. Please help! I'm losing
my sanity.

This is a charger other than what Garmin gives you? Does is charge properly
with the regular charger? Does is charge with the USB from the computer?
Does it charge with the power cord for the car (the one that goes in the
mounting bracket?

I'd suspect the charger. Just because it works with your phone does not
meat is will work with another appliance. Try a different charger.

What happens is when I connect the cell phone power plug to the squareish
power hole in the nuvi the maps instantly dissappear.

I don't know if the nuvi charges but what I want is the maps to show up as
I'm driving and need to know where I'm going for more than just a few
hours. Its the whole reason I bought the gps which was to see the maps not
some computer symbol on the screen when its powered up. I don't get it.

Why would the maps just simply go away when I connect the to power and then
instantly come back when I disconnect the power? Wierd.

Obviously your cell phone charger is not compatible. While many cell phone
chargers with mini type B USB plugs will work (I use the one for my Motorola
RAZR with great success), some apparently don't.

Use the one Garmin provided.

My guess is that the screen blanks because the presence of the plug is
disconnecting the internal battery, but either the correct voltage is not
present at the correct pin, or your phone charger cannot supply enough
current and the voltage output drops (assuming you haven't popped a fuse in
the charger or the car). The result is that insufficient power is available
to the unit, and it can't run properly. Depending on the pinout of your
charger, it is also possible that you could cause damage to the GPS unit
(although I doubt it), so I don't recommend trying this again.

I use my 360 in the car with the Garmin charger all the time.

Use the Garmin one, not a cell phone one. It sounds incompatible.
Hopefully you haven't damaged the Nuvi.

Not weird, really. That is not the method that should be used. There is a
jack on the back of the unit that contact with the power when you put the
unit in the mounting bracket. It is designed to use that power course both
for continuing power and to charge as you drive.

Try it their way. Some engineer got paid big bucks to make it work that
way.

I'd guess that it is because your cell phone charger, despite using
the same connector, puts voltage on different pins, destroying
circuitry in the Garmin.

Before you destroy another one, I'd try it with the adapter made to
Garmin specs for the unit; you are lucky that you aren't being charged
for the units you are destroying; if you told me what you have told on
this thread, I certainly wouldn't replace another one. I'd hook it up
in my control with the Garmin adapter, and if it worked, it would then
be yours if you used another connector.

That is called the Mass Storage Mode on some Garmins. It is selected
from a menu instead of the GPS automatically going into it when power is
applied to the USB port.

In the Mass Storage Mode the main memory and memory card in the GPS are
seen as removable drives under Windows and you can copy data to and from
the GPS.

I guess the assumption is that the you would not connect it to a USB
port in an automobile but use the power from the cradle.

Oh. I didn't realize that the power is different than the charging.

That's too bad because now I have to carry an extra power cord everywhere I
travel. If I kept the garmin permanently in one car that wouldn't be so bad
but I travel a lot and I was hoping to use the existing phone power
connection since it was the squarish usb plug. Too bad. That makes it a
little less useful than I thought it would be but at least it's not broken.
No harm seems to have been done.

Is there a better (more expensive?) garmin that does use the usb squarish
plug for power?

Sorry. I was on a trip. With my garmin. And the usb telephone power I
always carry. The garmin died. I then charged it. It died. I charged it. It
died. I charged it. So, that's my use model today.

I get a few hours of use then my (radio wave) eyes are shut while the
garmin charges. Then I get a few more hours of use. Then I have to shut it
down to charge it. Then I get a few more hours of use. And so on.

Luckily, the unit doesn't seem to have been "destroyed" by plugging the
telephone charger into the usb recepticle. It just charges.

It would be better for my particular driving style if the usb also powered
the garmin at the same time it charged like the (otherwise inferior) TomTom
One does.

Thanks. The good news is that it didn't destroy anything since it was just
usb anyway.

It was just wierd that what I thought was the power put the garmin into
Mass Storage Mode. It would be better if there were a switch that allowed
YOU the user to determine whether you decided on power into the USB
switching it into Mass Storage Mode or Power Input Mode.

May I ask the following related question of you all?

QUESTION:
Would it make the Garmin more user friendly to you if there were a setting
that allowed you to select whether the USB plug would function as Mass
Storage Mode or Power Input Mode? That way, you could use it either way.

Thanks Doug for answering a question I wanted to post to this group. I
just bought a 670 and was wondering if my RAZR adaptors would work in
the car AND at home... I'll be traveling for a while in Europe and this
saves me from taking one more piece of electronics with me...

Do you notice any time difference in charging using the Motorola RAZR
adaptor vs the Garmin provided charger?

Thanks again,

On my 76Cx, you have to choose to put the GPS it in the Mass Storage
Mode when you have it connected to a USB port. The main reason for
doing that is so you can open, copy, or delete the *.gpx track log files
that are on the microSD card.

When the 76Cx is USB connected and not in the Mass Storage Mode, you can
use MapSource to upload supplemental detail map files. And you can use
MapSource and other GPS utilities to upload and download routes,
waypoints, and tracks

And the 76Cx will also run off of the USB port's 5V power while it is
connected instead of using the internal AA cells that are its normal
primary power source. It does not charge the cells, it just does not
use them when power can be taken from a USB port.

The nuvi do not collect track data and you cannot upload routes to them
so there is little or no use for the nuvi to be able to operate in any
mode except the Mass Storage Mode (for mp3's and jpg's) when it is USB
connected.

The nuvii were aimed at users who wanted a simpler device so they left a
lot of settings and preferences and some navigation features off from
the earlier models. At the same time, they were adding what I call the
"brain candy" features like the photo viewer and the mp3 player. So
they probably figured that the automatic Mass Storage Mode was a good
thing for person looking for a simpler device.

It might be more friendly to the people that want it that way. But what
about the little fat faced teen aged girl who is driving around digging
mp3's and looking at images from a slumber party? You know, the one
that is about 3" off your bumper and 2-3 feet out to the left in the
hopes that by some miracle a new passing lane will show up?

What if she had to spend another 5-10 seconds in a menu to get into the
Mass Storage Mode so she could update her mp3 files? What if she was
like all traumatized by the complication and delay and got some bad
grades? Garmin might incur some liability. And she might tell her
Daddy to buy her a different model and it might not be a Garmin.

There is a lot at stake here...

Note that I did order the optional AC charger for my Nuvi 650. While the
unit is unusable as a GPS while plugged in to my computer with the USB
cable, the 650 still works perfectly while being powered and charged by the
Garmin AC adapter, which also uses the same USB plug. Apparently the GPS
knows the difference.

If you use the Garmin AC adapter, it does work in "power input mode".

less sophisitcate, larger, cheaper, my C330 does run and charge from a
COMPUTER USB cable.

As for the running ... powers on, but I am not sure the receiver
tracks satellites. It switches from its charging display (off) to
charged display (off) after it thinks the battery is fully charged; I
don't have any way to measure to see if it is correct, but feel it is.

That's a sad thing. It is bad when they are alone in the car. It can
get out of control real quick when there are three or four of them and
they are interacting.

The driver's education programs are in shambles here where I live. Not
one single child has ever not received credit for successfully
completing the course. The instructors have no certifications and, for
the most part, are about the same age as the kids they are teaching.

I ride a motorcycle frequently, the very young and very old drivers are
my bane. And the moose too. Oh, and porcupines. And the big fat
beavers. Some of those beavers must go 40-50 pounds.

Thanks SFB for stating just what I would have stated, which is, for well
designed products, there should be no need to carry any extra power supply
when the garmin already has a usb port for charging.

From my accidental experience, it seems that the charging time is just a
few hours so it's online for about 4 hours, offline for about 2 to 4 hours,
then back online again, then off, then on, then off, then on, and so on.

If only the garmin would both charge and work at the same time!

Unfortunately I have no idea. I assume some pin not needed for power is
telling the unit that it's hooked up to a USB port. When connected to the
Garmin AC adapter, it both charges and continues to be useable as a GPS.

It will, but not with the USB port. It charges with the 12V connector

Well, actually, I haven't yet used the RAZR's car charger in the car, I've
only used the Garmin one. I have been charging my 360 at home with the RAZR
AC charger from the get-go, so I can't honestly say if there's a difference.
What I can say is that the charging process appeared to behave as expected
when using the RAZR's AC charger (I am an electrical engineer who works with
a lot of battery-powered equipment, so I keep my eyes open for anything
unusual).

The current rating on the Garmin AC charger is slightly higher, so there is
a possibility that the charging time could be faster, but I haven't tried to
compare them. In any case, I wouldn't expect much of a difference.

Since the charging is regulated by the GPS unit itself, the only thing the
charger has to do is supply 5V with enough current to charge on the right
connector pins. Nowadays, that's easy since (I've found) the chargers using
the mini-B plug tend to be fairly standard.

My 330 charges the battery and runs the unit hooked to my laptop. Runs
means that I can upload and download; I dont' know if the reciever is
on, but I THINK it is.

If I've run it a while on battery, plug it in to the car mount, it
turns on and runs. When I turn it off after 4 or 5 hours, it seems to
be fully charged. Note ... NOT through the USB port ...

Mine will fully charge either with the USB cable or the car charger.

The real question is why would you risk damaging your Nuvi by using a cell phone
charger instead of the cables etc supplied with your Nuvi?

Use the right right cables/cigarette lighter plug supplied with the Nuvi, and if
you haven't stuffed it all will be well

and works - whats your problem?

Your plugging into the wrong port. The port on the side of the 350 is for
the PC cable. It will charge from there, but thinks you are in PC mode, so
shuts the mapping software down in anticipation of new SW. You need to use
the port in the back, with the supplied plastic part used to connect to the
mount.

I also recommend you use the supplied power plug, as the pinouts may not be
the same as your cell phone.

John, you can disconnect the plug from the mount and plug it straight into the
side port on the Nuvi 310 - works fine when you want to hand it over to a
passenger etc
