I have found something to try **For those that are having this
problem with the GPS receiver not being automatically detected each time the iGo is run, follow these simple steps:
-Open up iGo and go to Settings -> GPS
-Click on the AUTODETECT which will automatically find your GPS receiver.
-After it is detected, write down the PORT and BAUD values.
-Place the GPS SD card in your computer and navigate to the sys.text file in the iGo8 folder
-Find the header labeled: [gps].
-Underneath this header, it will have: port="x" and baud="x"
-Replace the values in sys.txt with the values you found in the GPS unit after doing the Autodetect.
This will ensure that it defaults to the correct port and settings to find the GPS receiver each and every time you load the software.
