I Have A 8310 And My Gps Usually Works Fine But It Will Not Work In The Co-pilot App. I Am Using The Beta 4.5; Could That Be The Problem? Also Is There Any Way To Get The Old Version Of Google Maps, It Seemed To Be More Accurate Than The New One.
I tried the Gateway connection (unlocked 8310) and it didn't work for me (my built in GPS isn't recognized by MapQuest Navigator either). Although I have BIS on T-Mobile. Garmin Mobile & Google Maps detect the GPS just fine.
However it worked just fine on my curve 8320 with bluetooth GPS (Freedom Keychain GPS 2000).
