sound quality is perfect and the pairing is automatic its realy nice upgrade

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!

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

that would be really nice.

actually i don´t really understand the problem in my case.

it should work.

this is my setup in stock condition:

The antenna is still connected, i removed the retrofitted SES system and the eject box but the system wasn´t 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

Perhaps start a new thread with your ipod question.

Yup... BITII wiring is totally different at the 54-pin plug. You can either re-pin the plug or make an adapter.

I have an adapter between the cars wiring and the retrofitted SES system. so i guess i will choose the adapter at the tcu side to be changed.

Or its easier to get any 54 pin adapter from scrap .this will help you to keep the original wires untouched

I learned some TCU's are not designed to work with MKIV . I dont know how far your work is. But if you created the new wiring you can test it by searching for it on ur mobile

If ur mobile detects and connects then this TCU will not work with MKIV.

What do you mean exactly? i did the re-wiring and its still not recognized. i use a mk4, yes.

so you think i should replug the tcu (its currently not in the car) and try to find it at my mobile even if the TCU won´t be shown or found within NavCoder?
