I have my alpine double din up for sale. Purchased in 2013. Used for about 2 months to be exact and then sold vehicle. Removed all my sound which was In the vehicle valued to about 30k. This double din alone costed my 8k and with the ad on of nav and Bluetooth it was an additional 6k. I'm selling the double din with the nav and Bluetooth module for 8k. It has all the features you can think of and if you in search of sound quality then you will never go wrong with alpine. I have all the manuals,disc,wiring etc. It's in the box. There is not a single defect with this unit. Price not negotiable. Call only if interested on 712 - show phone - 4.
