Hi I have a semi decent Alpine IVA-D300 the reason I say semi is because the monitor has a small problem. Every thing as far as touch and menu options and the display are fine the only problem is the screen coming out and going in. It needs help coming out and help going in it flips up and down on its own just retracting into it self is the only problem. This can be fixed at your local electronic repair shop if they work on car units for should be no more than 80 bucks. It comes with brain and all wires. So your getting a Alpine D300 for 420 bucks still a great deal. No other problems brain is fully fuctional in every aspect. Thank you.
