Im sure this has been answer before, but for some reason i cant do a search. I install a after pioneer indash tv in my 02 max.. After the install my steering wheel control for the onboard computer like DTE or MPG aren't working. Is there a way to fix this problem? Thanks!

 

for the trip meter stuff just ground the brown wire with a white stripe on it from the harness not being used. to get the steering wheel audio controls to work buy the pac swix adapter.
