I'm a member of driveaccord.net and the moderator there told me to check to see if any members on this site woukd have come accross my delima. I have provisionally installed Nav unit on my non nav Accord 2.4L EXL. Every things works fine except my HVAC or AC is greyed out on the touch screen and the other touch function of air flow direction are greyed also, however the push buttons at bottom work well except for the AC. Any ideas why the AC touch on the screen dosn't work. Also connected to the unit are the HVAC two stock blue connector from the original car harness without any modification. I was told that the HVAC system on the EXL (Non Navi) dosn't require any modification since the harness is the same. Look at pictures I posted here.
