Ok so im looking to get a touch screen navigation/mp3 unit to put into my center console. All Im looking for out of it is navigation and the use of my ipod, and possibly even better sound quality. Im thinking the install/fabrication will cost about 100$ and i only wanted to spend 3-400$ max. I found a unit for 170$ which is a sick price, let me know wut you think, is it a cheap piece of garbage, should i get another one, if so which?
Thanx!
