This is for 2002 C5 allroad.
I retrofitted the RNS-E, Sirius, OEM BT and everything works/programmed/functions properly.
But I was wondering if this switch could be somehow enabled on a software level? That would be very convenient to be able to use some of the shortcuts from the center console

Thanks

Blimey, this question used to asked a lot but hasn't been asked for many years.

Sadly, the answer is still the same - no.

I disassembled one to figure out if it can be done and it can, but there would be tons of wiring and soldering or else I would be all over it.

How would you connect the switches into the internals of the RNS-E without tearing that apart?

It won't take CAN bus commands to control it so there's no other way AFAIK.

This would be hardwired to the RNS-E's mainboard. So essentially, I would run wires from each of the buttons on the console to the corresponding RNS-E button and tap into the connections at the motherboard. Like I said, it would be a pain in the ass, but it would be nice to have.

You're not kidding, it would also be a nightmare to get the wires out of the RNS-E, fit a connector (so that you could remove it) and attach the wires to the buttons.

More pain than it's worth IMHO.

Yup, definitely more work than I would want to undertake. However, I would do it if I felt 25% more confident in my electrical abilities lol.

I wouldn't do it and I'm a Chartered Electrical Engineer with 30+ years experience and ex-Chief Engineer for Nokia - as I know it would end up looking like a complete rats nest of wires.
