I've had one of these fitted in my car for a while now and I find it a great head unit for the price.
it will skip a bit if I hit a big bump (my car has lowered suspension so this might not be a problem in an average car).
Some menu items are a bit tricky to access.
If I select random play while a track is on it will immediately stop that track and go to the next (random) track.
The tone controls are good.
Easy 'telephone mute' mode
