Garmin (be able to upload gpx files to the iphone) and give you turn
by turn directions?
I'm trying to decide if I need to spend another chunk of change on a
Garmin 800 or if I can accomplish the same thing with my Iphone.
Thanks

Motion-X GPS will let you upload a route and will show you where you are on it. It can also cache maps, so it will work when there's no cell signal ... like on Kitchen Creek road out here in San Diego County.

G'day Scott
Following is the text of my recent post to the Audax Oz list. It's not
been edited for local references but some it might be of use to you and
others on this list. Have fun. Oh and Garmin makes an iphone dongle for
receiving ANT+ signals. The photo that I saw most definitely shows that
it doesn't have a iphone socket so that it can't be charged on the move.
Have fun.

Early this year I bought an iphone linked to Telstra 3G. Thought was
given to using its GPS capabilities on rides so the Cyclemeter app was
bought and installed and the B&M Ewerk plus battery was installed on the
recumbent to keep the ifone battery topped up. Battery life isn't
wonderful when not much is happening and would be less so when
processing the GPS data. The batphone is parked under the lid of the
rack bag where it has a very good view of the sky. This solution is only
suitable for good weather as most mobile phone offerings are far from
water resistant.
The app does a fine job of keeping track of where I am in 3 dimensions
though I'm not confident of the accuracy of GPS derived altitude.
Cyclemeter generates a .gpx file which can be processed by, say,
ridewithgps.com
As an example my plot of this year's Flat 400 is at:
http://ridewithgps.com/trips/249050
Cyclemeter is happy to plot other activities like runs, walks, car trips
etc.
A minor annoyance of the system is that Cyclemeter files have to be sent
by email. Dunno if this is Apple being precious or a limitation of the
app. I reckon having email come to ones batphone is a bit onanistic so a
send-only webmail account had to be set up.
AFAIK Cyclemeter is available for other allegedly-smart phone platforms
and there are other apps that provide similar functionality but I've not
tried them.
The ifone GPS feature has other uses. There can be times when one is not
10,000 basis points confident that one is not geographically embarrassed
and a quick spot check is necessary. Telstra 3G has provided me with my
location on a Google Map every time I've tried in rural Vic and SA.
Other carriers may not be able to offer such a boast. Of course a
porpoise built GPS jigger will do the same from its internal map.
Heart rate, speed and cadence can be ported to the ifone and other
platforms with a dongle that will receive ANT+ signals and, of course,
suitable ANT+ sensors. Wahoo is one. I haven't checked these systems
closely but the dongle would need to have a female socket at the other
end so the battery could be kept alive on an Audax length ride.
This system works well in Oz where 3G data feeds are cheap. OS data
feeds are fiendishly expensive so a bike GPS is the only realistic option.
Notwithstanding the above I'm moving to a Garmin 800 device soon. Some
of its attractions are:
Water resistance
Charge on the go
Entertainment value on the handlebars
Native use of ANT+
Others can rabbit on about their Garmins.
Hope this helps.
