Ok, so minus the TTS voice (the option for TTSPro in the settings is greyed out), it worked great last night and this morning. On my way home from work today, it couldn't maintain a GPS lock. It was like lock for a second, then lose it, the lock for a second, etc. Check the GPS Information app on the head unit, it showed that had very good connection with 10 satellites. The signal was fluctuating just a little bit, but not more than 2-3%. I restarted iGo, rebooted the head unit, and it didn't change. This is a brand new unit, and I understand there might be some flaws, but every other GPS software I have tried NEVER has an issue with positioning...
