Please help.

About a month ago, I had the dreadful "CD ERR", I replaced the HU.

After new HU installed, HVAC and HU display not working.

Then I replaced the circuit board, still HVAC and HU not working.

Any ideas on what to do next?

Any help apprecaited; thanks.

 

My next guess would be the HU is broken.

 

That's what I am worried about, I am going to try and reconnect my old HU to the new and old circuit board.

Thanks.

 

Keep us updated thanks

 

Will do.

Has anyone else experienced this problem yet? I talke to the shop foreman at the dealership and he said the there is a good chacne that it is the HU....stay tuned.
