What is ABP, out of curiousity?
I have a Sony Xplod CA-650X, I love it. Great features, attractive looks, cheap price, solid 52x4 performance to my stock speakers
Only complaint, the LCD doesn't illuminate anywhere nearly enough during the daytime, especially when the sun is blazing right down onto it... I can't see a thing.
Perhaps some tinted sheets will take care of this... other than that, I definitely recommend it if you just want a good mid-range head unit.
