I was wondering what would be better to do. Get a PDA with GPS built in or get an in-dash lcd tv with GPS? I have an 04 Stang GT with Mach 460. And if I was going the PDA route, I would probably get the Garmin iQue 3600. However, I do not like having cords all over the place. Not to mention, there will be something stuck to the windshield. However, the cost is very low, but the screen is small. Now, I could go the more expansive route and get the in-dash. Probably the Pioneer all in one model or go Kenwood and get theirs. However, could I be able to fit 2 recievers (Navigation and LCD moniter) into the old mach 460 area? Also, would I need to replace my factory amp? I also want to get a 6+ cd changer as well. I dont konw . Each has their pros and cons... so what would you guys perfer?
