I purchased for the navigation functions and MP3 capability. Unfortunately, you cannot use both at the same time. You can play the radio while using the Nav, but you're stuck with the limitation of plain radio. You also cannot use the CD player at the same time as the navigation system. So basically the unit is a single function unit. It does one thing well at a time, but do not ask it to multitask.

well this didnt last long not good sound but i like the gps system

really guud quality product, has everything i was looking for
