I went back to the shop to try to get the Off Hook and On Hook/Back buttons working again.

 

This time I stood there while the tech set things the way I liked, image below.

 

Those two buttons still don't work. Everything else works fine.

 

Any clues?

• 2014 Honda CR-V (came with Base head unit)
• AVIC-5000NEX (1.08 firmware)
• iDataLink Maestro RR with the following settings:

 

 

Make sure you're getting various resistances from the RR SWI CIRCUIT 2 lead to ground, both while not pressing any button and also while pressing each "bluetooth" button individually.

 

My CR-Z has separate resistor networks for shuttle and bluetooth.  I opted for the custom programming; had to enter resistance values... but I noticed the wiring diagram for your vehicle shows connection to the CAN2L bus instead of shuttle resistor network (typically SWI CIRCUIT 1), so I don't know if custom programming is possible.
