This is driving me mad.

I pulled the RNSE out and found the car was fitted with a Kufatec ‘Basic Plus’ Bluetooth module.

I also found that two spare wires had been spliced into the Tel+ and Tel- connections on the back of the unit. When I removed the unit, the other ends fell out and I now don’t know where they were connected.

Now when I turn on the RNSE, I get feedback through the rear speakers. Further, when I phone someone, they can hear me through the mic but I can’t hear them as the unit shows it’s muted.

Any ideas where these two wires are meant to be tied into ? From another thread I saw that only the front speakers mute and so I’m wondering if this made the rear speakers do the same?

Thanks gents !

Ok

Now I think this could be less complicated than I originally thought. I get feedback through only the rear speakers as soon as I attach the wiring loom for the Kufatec BT Basic Plus. Has anyone heard of this before?
