I had the same problem after changing the radio to a DAB radio. I have been informed by Nissan Norway that the Bluetooth module is built in the original radio ( Daewoo AGC OU71RF ).
I have installed a Connects2 CTSNS010.2 steering wheel interface. The steering wheel buttons work but are mixed up. I am going to try a different interface the next time I am in England.
A helpful support person at Connects2 has confirmed that their CTSNS010.2 steering wheel interface isn't tested/confirmed working with anything other than NV200s that were supplied with the OEM Clarion/Blaupunkt radio.
I'm a little bit confused by that, given that I think the Daewoo radios have been supplied as the basic radio since at least early 2017 (if not earlier?)
Anyway, as a result, I've ordered a basic wiring harness for my new receiver, just so that I can get stuff working.
However, I'd be really interested if anyone has any experience of a working steering wheel control adapter with an aftermarket radio and new-ish NV200 - I guess there must be some about?
And...it works fine :smile: . Track selection, volume up/down, source selection and call answer all work with my new Kenwood receiver. Not entirely sure what the info button was used for with the OEM radio, but that doesn't seem to do anything with the new one.
