If you are running V1.3.0 or higher you jst emove the SD Card and the GPS wll be resetted.
For hooking up you Nano to your computer to communicate you need a FTDI cable. The USB is oly used for charging.

You don't need an FTDI cable for normal use. That is unless you plan to reprogram your bGeigie.
To upload the data you collect, take out the microSD card and plug it into an appropriate reader/adapter. Most computers these days include an SD card slot.
The reset procedure Rob mentioned (ver 1.3.0 and later) is easy:
1) turn off the bGeigie.
2) remove the SD card
3) turn on the bGeigie.
4) leave it on one minute
5) turn off again
6) put in the SD card
During step 4, after about 10 seconds, the display will show a message "NO SD CARD/GPS Reset".
(Powering up the unit without the SD card causes a error and a general re-initialization including the GPS controller.)

hi Kelly,
>Where can I find out if my nano is V1.3.0?
-- the firmware version in your Nano appears on OLED's startup display and on top of the log file in #header line
(BTW this is mentioned in the nano wiki https://github.com/Safecast/bGeigieNanoKit/wiki/Nano-Operation-Manual)
-- the latest available firmware version is found in the github archive
> browse to HEX file (the current version of the Nano firmware which is the bGeigieNano.hex file in the bGeigieNanoKit repository. (Today's version, "HEX for 1.3.4" -- 8 days ago)
? [kind] of store can I get an FTDI cable? Amazon?
-- see https://github.com/Safecast/bGeigieNanoKit/wiki/How-to-setup-build-environment-on-Mac-OS-X the FTDI breakout board 3.3V links (this one or that one) lead to sparkfun, a big online electonics store. The link to supplier is also mentioned in https://github.com/Safecast/bGeigieNanoKit/wiki/Parts-and-accessories
Upgrading firmware requires the correct FTDI breakout board. Whether upgrading firmware is necessary is another question.[??] My guess your current firmware is okay , if the nano works, and you’re not adding options, and there wasnt some critical upgrade. Watch or search devices for Rob’s announcements of new versions or look around github master for possible notes on changes.
According to above thread, resetting GPS doesn’t require FTDI. (Maybe someone will add the new info on reset GPS by turning on Nano without the sd card into the nano wiki.)
it's good to query devices group, to elicit shorthand support and also new info from core designers and experts like Rob Oudendijk and Joe Morass.
However, the Nano has a wiki for the community to update manual (ideally the pages would be concise and comprehensive). As it’s edited also by novice users, caveat the wiki may be wrong, besides verbose and out-of-date.
Maybe someone will make a movie showing the firmware upgrade to make it explicit for first-timers. (I use win7 not a Mac.)
Again the wiki link https://github.com/Safecast/bGeigieNanoKit/wiki/_pages as seen on the nano page http://nano.safecast.org, closes this RTM (Read the Manual),
( ps The second firmware upgrade goes very fast compared to first time at FTDI hex flash.)

Don't just copy what is written there on the third line ( -A700eYeV).
Good luck!
- Connect the bGeigienano with FTDI cable
- Unzip the attached zip file and double click bGeigeiNano_V1.3.4_uploader.app
- A window will open up and the bGeigienano hex will be uploaded to your Nano
