Just wondering will it work reverse as well ? I own a 2011 Z Roadster with Bose system no navigation i bought a used navigation set from a 2009 Z
as far as i saw everything fits except the climate control of course as you said its doesn't communicate directly as the old one but with Can BUS. So i am wondering would be possible to rewire the connector to the AC/ECU to make it happen ? or can i just forget about that dream and get rid of it? if anyone has any info about it would really appreciate it
Thanks a Lot!

This is due to the subsystems that need to be added like the GPS antenna, ECU inputs into the NAV system, and a few more. Also all eBay sales of the factory nav system that I have seen do not include the GPS antenna. The GPS antenna is not the antenna that is on the roof, it is actually in the dash above the HVAC fan/ glove box. Depending on which system are starting with you might need a new steering wheel too so you can have useable steering wheel controls.
