Hi JJ here in my West Coast I fitted a pioneer AVIC-F70DAB digital radio with navigation system and Bluetooth the system takes two cameras I have one to reversing and one at the front so that I can park close to the curb it's a great unit I have hands-free phone DVD player, and you can have a screensaver as well but the best thing you can set the uni up so it tells you if you're speeding, it's a 7 inch screen and easy to set up, I was going to buy the Alpine 8 inch but it means losing the cup holders and I need them for me drinks, there is an amplifier in the unit, I removed the old CD stack unit and the amplifier, I have fitted JL AUDIO 280 watts 4-channel amplifier as well, new unit and amplifier are still wired up to the fibre optic cable which works great with my boses speakers.
