Help!!! TCU!!!

KUMAR'S BIMMER · 04-17-2014, 03:59 PM

Hey guys!!! I have a 2006 330xi and I'm trying to retrofit bluetooth and found some tcu on eBay. I have seen tons of them for e60, e65 same year as my car. Would these work in my car or do I need a special one?? I also have logic 7 if that makes any difference.

to retrofit Bluetooth in your car either you need TCU or MULF. However since your car was produced in 2006 I would recommend to do software update first. Logic7 got nothing to do with it.
As to money wise, it makes a difference if your car is prewired or not.

It is pre wired, but what I want to know is a tcu from a 06 750 would work with my car?

check part numbers in realoem.com

I've tried that and all the part numbers are different for tcu

It would be easier to go aftermarket
A Dension 500s bt would give you bluetooth phone / streaming bluetooth
music and usb/ipod.
There is a similar unit from mobridge.
See there website.

If you have a pro radio there is a new version that has bluetooth usb
and Hd radio built in but it requires some programming and you must
get one with most bus to be compatible with L7.

If you still want to go OEM read the bluetooth thread and a MULF2
or some variation at least you can get USB/ipod/bluetooth with that.
It may require a different wiring harness though.
