How'd it go? Does it all work now? Did they have to change the buttons or rewire?
I have my unit mostly working now, but my steering wheel buttons produce no response - just like you said. I have the phone/OK bottom button that is supposed to be correct, I believe for '09 also, but have been told it needs to be wired directly to the Nav unit, not the APIM (Sync) as it is on an '08. Phone works thru Nav/radio OK, though.
Still need an '09 Nav/Sirius antenna for mine. I now get Sirius, but no GPS signal. I added the signal "splitter" for an '09, but think the antenna only tuned for Sirius ...
Anyone know where to get one reasonably priced?
