I found an Japanese NEC interface module with associated cabling in my car. Is it or the cabling of any use to me when trying to get bluetooth in the car?
Here's the background:
My A6 (Japanese spec) has no bluetooth but has this cable in the center console.
I always suspected there was some kind of module beneath it but have never able to access it until now. I have now found an NEC Interface Handy 4E1 862 335 in the center console below the cable.
What is this for?
I don't have bluetooth in the car but I want to install it. Will the Handy help with this? I suspect the Handy might have something to do with Telephony.
If the module is not of use can I utilise the cabling that existing in the centre console?
Thanks in advance
