I have recently swapped the 4" base unit to the 8" Sync3 with GPS nav. There are some issues with the GPS nav that leads me to suspect the antenna. Those that have done this swap, what antenna did you use?
Thanks for the recommendation. For whatever reason, the gps nav has been working flawlessly for a few days. I'm going to see if this trend lasts.
I other news, I installed the latest version of Sync3 and the latest maps using the cyanlabs tool. Worked like a champ. It's all kind of coming together.
