Hi guys,

So I've just installed a 9W7 kit in my 2009 Tiguan. The module is above the climatronic and plugged in. I had a DIY harness which I have spliced as per this pic. I have plugged into the BT module, the mic and the RNS510.

Now, the RNS-510 powers on fine and works as previously.

I go into VCDS, 77 - Telephone is already checked in Installations for CAN Gateway.

But I can't go into the Telephone module in VCDS. It isn't picking it up for some reason.

Is there any way to trouble shoot here? I'll jump in with a multi-meter tomorrow and make sure my solders are good. I can obviously check the power+ and gnd but is there a voltage CAN +/- will throw out or a way to check?

Tips appreciated please.

Cam.
