when i checked the MKIV after assembling every thing the telephone menu keeps showing please wait!! then i tried to connect it without the adapter and kept the same after i searched on my mobile for bluetooth devices it did finaly connected!!! the funny thing that i spent more than houre making that adapter and it was just a mater of a plug and play!!:rolleyes:

sound quality is perfect and the pairing is automatic its realy nice upgrade :thumbup: many thanks guys

any way am very happy with it ,just only i couldnt find search function within the contacts list!! do i have to do some update or programing?

ah before i forget plz ca nyou help me with the pinout for the OEM IPod interface, i need to make the cable that connects the IPod to the interface my retrofit is missing the cable!


So it did work even without the adapter? did you use the bit2 adapter?

yes its working great, you don't need to build an adapter 4 it, its just a plug and play, just make sure you did remove telephone holder and disconnect the wires, don't need them and keep the antenna connected, its located under the arm rest.

good luck

The antenna is still connected, i removed the retrofitted SES system and the eject box but the system wasnīt recognized in inpa.

i plugged the 54pin connector and the cream antenna connector. what do i have to do with the unwrapped purple facra and the former used "antenna" style cable?

thanks alot for your help :)

your Bit II is exactly like mine.. this means the cable retrofit should be the same 2, can you post a picture of your TCU?

and can you tell me what's your ride and which year is it?

My friend i do beleive that ur TCU is defferent and you need to figure out the wiring 4 it.. this means u need to build an adapter after u get the wiring map right.. ill try to search 4 the pinout 4 it, do you know which car mobel and you get it from?

Cloudforce 12-28-2012 05:02 PM

It is different to other TCUs i have seen:

http://www.abload.de/img/tcu5yuzx.jpg

sadly the VIN was removed, so i just found:

sadly my favourite wiring diagram site is offline, otherwise i would have searched myself about rewiring. :(

wsramahi 12-28-2012 05:09 PM

So far its clear that the fuse burns becouse 1 of the 3 power wires get shorted when u connect the cable.i'll try to check the wiring for everest TCU. Hope ill get something
