This dual radio navigation radio system is out dated you can not update without having a lot of trouble with the dvd softwear disk. All infomation is deleted from the SD memory card and it will not work. The Bluetooth does not work there is loud feedback and loud echo from it. the video screen will not come up when you first start the car there is black edges and it goes at a twist you can't see the screen and it is very dark. Not worth the trouble. I guess i will install it in a farm truck so the cows can watch it.

i received this product had it installed in my vehicle the radio worked, and the navi worked thats it nonthing else worked.

Nothing but trouble. It was a good price, but broke after 8 months. I had to remove and send it back for a refund and since I had lost the remote I lost a few bucks. I instead went with a quality head unit from a name I could trust (not dual).
