i just recently installed this unit in my 99 pontiac grand prix GT. i have aftermarket highs, mids, and subs in the trunk. i always thought my system sounded great but when i installed this head unit in i noticed a more clearer sound. im amazed at it. though it will take you a minute to figure out how to use it. The bluetooth is great too. i can hear the other person clear as can be and they can hear me too just as if i was talking directly on the phone. The only draw back is that when installing this unit cause of the size you have to do some pushing and pulling and moving of wires to get it to fit. I would definitly recommend this unit to anyone.
Love the site. Categories are well broken down to detail for exact applications. Couldn't be done any better. Excellent and fast service. Can't wait to get my HU installed. Thanks for the deal.
