Bringing this back up because myself and at least one other are interested in this unit for replacing the 8.4. I suppose what I need to figure out is:
1. Maestro has released the CHR03 unit which now covers 8.4 replacement.
2. Alpine has their own head unit, the X009, which I assume uses the above unit, or something very similar, to perform the vehicle interfacing duties.
As I understand, everything works with the exception of the HVAC position controls. I believe those statements were made before the release of the CHR03 product(?) So what I now need to figure out is; have the HVAC specific CAN commands been integrated into the Maestro since? If so, do any of the aftermarket offerings (Alpine/Kenwood) provide the radio GUI's to even perform such functions?
In looking through the latest CHR03 manual, it reads:
"To access the Maestro menu, press and hold the Favorites button for 3 seconds. Press on Climate to display information about the climate controls. Depending on the OEM climate system, the status of the climate controls is able to be shown or controlled in some vehicles."
Rather vague regarding the position stuff, but the GUI shown in the manual does seem depict different positional options for the HVAC.. I'm just not sure if this is a generic photo. I guess I'll email them and see, unless someone here has purchased the unit and knows for sure.
