I received my new DVD navigation system yesterday. I bought it from an online store. It should be the same as the QL-MZD723 (autodvdgps).

It is very easy to install. The first thing I did was the setting of the steering wheel control. It works fine.

It has a lot of functions and interface like, navigation system (for example iGO), DVD, DVB-T, Bluetooth, iPhone/iPod support, USB, microSD card reader etc. It should also support BOSE sound system.
