Acura Repair Questions? Ask a Mechanic for Answers ASAP
Hello welcome to just answer I am master tech and will do my best to assist you today.
not sure on your key issue which makes no sense unless you used the wrong key.
as far as the multi display unit this is a all in one if this has navi.
we can try a master reset by disconnecting the battery cables and use a wire to connect both battery cables together.
make sure to place something over the battery post so this does not make contact and short the entire system out,
this is critical that you pay close attention to this part ok.
most people will place a piece of cardboard over the battery while this is been done.
once you get these connected let this set for 20 minutes and then reconnect the battery and start the car up and let it reconnect with the gps.
can you also shed some light on what was done prior to this happening.
did anyone accidentally cross the cables on accident for a split second ?
now these items have since quit since the battery jump correct ?
now the navi been out now all the hvac functions have failed also.
so since this is all controlled through the navi display it will need to be repaired in order to regain full function of the hvac system
