I also bought the USB004 DAB+.
Questions:
Which cables from RNS315 connection can I re-use for the new unit? I think the radio one can be re-used to get FM/AM radio.
Do I need to connect the blue antenna power cable from xtrons unit to somewhere? If so, where does it go?
Do you know which of the other two cables are which? DAB, GPS? Is the blue one DAB, and remaining white one GPS?
Do I need additional FAKRA converting cables to plug them into the xtrons unit?
Do I need to do something with the ACC and BRAKE cables on the harness?
I am an amateur user, not a professional fitter, but enough sense to manage stereo install


Photo of cables in the car attached.
Thank you!
