I'm watching carefully your thread cause as of today i'm also the owner of a
Dynavin E9X which i'm planning to install it to my 335i.
I'm gonna go the DIY way so i'll post some pics on your thread if you don't mind in case you want to use them on your thread.
Here are a few of what i received today.
The Main Unit
The DVB-T Tuner in which i'd like to ask wether i should install both Antennas that it came with and what is the USB port for in the back of the tuner ??
The Main Wires, the remote control and a USB Extension Cable.
And the Bluetooth Mic, the Steering wheel buttons IR box, the IPOD cable, the GPS Antenna and 2 more USB Extensions.
Any suggestions of where to place the GPS Antenna and the 2 TV Antennas are VERY Welcomed. (As also about the USB, AV, and IPOD cables)
