Pioneer AVIC-F500BT / NavGate 500

Good quality nav unit - locates satellites very quickly, dosen't come with a case which is disappointing at this price. Will work with iphone but for control only, no audio via unit or video from iphone. The built in TMC is very good but only works if connected to the gateway amplifier, if used as a standalone with the supplied cigarette lighter adaptor then TMC is not available, this seems odd as the amp and the lighter lead both supply 5v to the unit.

Speed camera updates are available free for the first year but you need a SD card to add them to the unit.

Built in microphone for the bluetooth is a bit weak, constantly having to shout.

All in all a good unit, but not perfect. If your vehicle has a standard DIN socket then i'd change the factory unit but if you can't then there isn't much better at the moment.
