JVC Navigation has the added bonus of being able to have the front panel removed on their range of Double DIN navigation, unlike most Double DIN units where the unit stays fixed in the car.
The start up time on the new JVC KW-NT3 is an impressive 15 seconds meaning no long start up time.
The JVC navigation comes with Bluetooth built in and is fully compatible with both iPod and iPhone and will also support video playback via a video iPod lead.
