very nice!! :D

I believe that with #15 led retrofit with e92 you are able to code the same on the e70 for the new led tail lamps right?

Yes, you should be right, I never tried it but it must work according to what I was reading and comparing. Probably I will have to get eventually LED retrofit and code vehicle for test.

can you post a do it yourself guide when you finish testing?

Yes I can do that guide BUT I am a bit scared now about responcibility ;) Everyone who will be doing coding of their BMWs should understand that in case if you for some reason screw up your module (any module) because of bad power supply (yes you need or most probably will need a battery charger in order to perform coding) you will have to visit your dealer. Also there is a chance that the visit to your dealer will happen via toying truck. Once I am done with my tests and self education I will post information here.

Hey vinzer. I'm about to trade in my e53 for a e70. but the one im looking at has no nav. i read ur messege on how you successfully retrofitted your e70. can you tell me what to look for on ebay as well as what 3 wires you had to run. i wanna know i can do it b4 i get this car. the dealership seems to think it can't be done.

Yes it is possible to retrofit CCC in E70 in case if it come with no nav from factory.
You will need to buy CCC navigation from ebay. Technically you need only the screen and main module (CCC module). You also will need two cables - cable to connect display and CCC module (I will tell you how you can use your original existed cable if you do not want to buy new one). Another cable is the FAN cable, but I can also tell you how to build one your self if you want.

CCC Main Module: 07-2010 BMW OEM E70 X5 E71 X6 AT-CCC CD NAV / CD RADIO on eBay.ca (item 260667291811 end time 23-Sep-10 22:00:00 EDT)

CCC Display: ecran CID BMW X5 E70 navigation professionnal new on eBay.ca (item 120621665660 end time 24-Sep-10 15:35:42 EDT)

So far tested (in bold) and confirmed to work on my E70:

1.Enable remote folding mirrors and windows/sunroof opening/closing
2.Enable remote windows/sunroof opening/closing
3.Enable remote hardtop folding
4.Enable One-touch sunroof venting
5.Enable TV/DVD-in-motion (only for the CIC) - yes it is possible to instal CIC instead of CCC in E70 :thumbup:
6.Enable Euro front blinkers (disable US Sidemarkers)
7.Enable M3 digital speedometer in the instrument cluster
8.Enable any lights as your Welcome Lights
9.Enable remote trunk opening/closing
10.Disable iDrive warning
11.Disable door gong
12.Disable headlight washers
13.Disable a bulb check error (LED bulbs, HIDs, etc.)
14.Retrofit coding (OEM Alarm, Sirius, PDC etc.)
15.E9x LCI tail lights coding (all FRM versions)
16.Head Unit audio output coding (Stereo, HiFi, TopHiFi, Individual)

Especcially I loved the fact that after installing of the LED White Plate Lights I got an error message from the vehicle (obvious) that my plate light bulb is bad. I was able to code the vehicle the way so no longer error message appear on the screen.

Now I am planing to install H11 HID kit for my fog lights and also play around with coding in order to avoid error message.

Sounds great.
Do post a guide when you have the time, what part/cable we need, where to buy etc...
Just put a disclaimer on your guide, and you should be fine. I think everyone would understand the potential danger of fiddling around with the coding if something goes wrong.
