Sure. I will post some pictures. The way I did it was to cut the wires one by one (not all of them at once) and then connect a one foot cable (5 wires) to the connector and then run it to the glove box. I soldered all the wires in both ends. Don't forget the disconnect the battery if you do this extension. It's safer.
Now, a tip for the backup camera install, disconnect the battery when you do the install. I didn't and since I did the testing without the seat connected I got the airbag light on. I have carsoft so I should be able to clear it but to avoid this just do it right.

Hualingan has the option to surf the iPod but my units do not work with my iPod nano due to a cable issue. They are going to send me the new cables that supposed to work. I am not and iPod user so that's all I could test for this device. I will update the status when I get the new cables.

This is kinda off topic.. but i hear a lot of people saying the hualingan looks better than the Dynavin.. in my opinion the dynavin looks more OEM, but off course everyone has their own opinion.
Is the dynavin e39 made for the X5 (i know the hualingan is round shaped to fit in the x5) will the dynavin look good in a x5?

Can't seem to find the DYNAVIN unit on the bimmian.com site. Do they sell it? Would anyone know how much? International sales?

i dont think bimmian offers the dynavin unit

theyre out of stock for now but can keep you updated when they have it again

You don't want dynavin now that you cut the radio frame for Hualingan. I would stay with Hualingan if I were you. I am really happy with mine.
