Summary: This Item adds a lot of functionality but it is missing some key items. First, do not think you can add an aftermarket amp to this in the way you would a brand new deck. It does not have "preouts". Well it has one set but they are a fixed level, I.e you turn your system volume up but the volume of the Sub/amp will not change with it. Also no remote turn on wire, so you will need to run a new switched power source for your amp. The Bluetooth works great, at low speed.
Summary: I'm very very dissatisfied with this purchase the item is a total junk.. Quality of the sound 2/10. The mp3 player doesn't reproduce a complete playlist, you have to select no more than 10 songs. The Bluetooth hands free don't use the speakers of the car, it play the call in a built-in speaker that sound very low and if you have the music on you simply don't be advised that an incoming call is ringing.
Summary: Great unit for about the first 6 months. Then the touch screen was having problems in terms of accuracy. Calibrations would only temporarily fix the issue, now I calibrate nearly everytime I start the car. GPS would sometimes take several minutes to start tracking my position. Also take note that there will not be software updates so I will probably be stuck with these issues.
Summary: Total Waste of money. Worked fine for a month than the touch screen started to malfunction, now it's so bad that I cnt even navigate. No warranty , no replacement, and customer service is almost non existent.
