Last week I purchased the Kenwood KIV-BT900 head unit on ebay for less than $250.

Features include built in blue tooth, 3" led screen, and selectable color display to match the interior of any car. I highly recommend this unit to anyone looking to upgrade. It took me weeks of research to find the perfect unit and I would have to say that I have found it in.

Paid a shop $70 to install it and another $15 to bypass the e-brake which allows me to play videos/ movies while driving. Sound is much clearer than factory head unit while playing music and the bluetooth sounds crystal clear.

Pros - Plays music as well as videos.
Customizable display.
Built in bluetooth (Talk and text)
Sound quality is amazing.

Cons - Pricey if you cant find a good deal.
Doesnt play CD's (i assume most have an ipod/cell phone).
Literally has too many features to use immediately and requires you to read the manual (twice)
Made for Ipod and doesnt work well with Android platform.

Pictures are attached but they don't give justice to the clarity of the screen. Music videos and movies play in HD and look fantastic.
