Is This Cheap JBL Navigation Unit For Real?

I bought a Win CE based unit for my 2010 (non JBL) about two years ago - I never found an update for the NAV and now it quits or refuses to even start. So it's quite a gamble to buy one.

 

I bought a cheap Chinese navigation head unit about 6 months ago. It runs iGO navigation and seems to be pretty good. When I first got it I was kind of upset because I listen to a lot of AM sports radio and the turner was set for EU stations not the US. After some emailing with the seller I finally got the code from him to enter a hidden menu and get it changed. Since then it has been fine.

The only thing I don't like is the dimmer at night. It stated it would dim when the headlights are on, and it does, but it is maybe half a step dimmer. The thing is bright at night. I did find out if I hold in the mute button for a second or two it shuts the back light off completely until you touch the screen again. Also the instructions were terrible. It showed what wire went where, but that was it. No real instructions on how to operate it. I've just figured it out by hitting buttons.

It may quit working in a year, but paid around $300 for it on ebay.

I had to get it because my JBL amp quit working. Without the amp the JBL head unit is worthless. Pulled the JBL amp out, added an aftermarket amp, and an aftermarket navigation head unit.

This is the unit I got, but from a different seller.

 

Can you play your music through Bluetooth? I just leave an old iPod plugged into my car for tunes since I've been too lazy to sync up my music library to my phone.
