I purchase a Ouku HU it has a Navi, DVD, Ipod connection, Aux connection, SD card slot, Backup camera, Bluetooth, at the price of $219.00, I also had to purchase a DIC box for the car information read out for $200.00 it cost me $217.00 to have it all installed, now a month after the system have problems, when changing from my XM unit to radio the volume changes also, from low to high, that happen when changing from one thing to another, no matter what it is, I recommend not to purchase this HU at all, oh yeah the backup cam works sometimes
