I checked everything I could think of as to why my Touchscreen/Radio Controls
wasn't working.
I Disconnected the Battery for 2 hours the other day, replaced all the fuses one
at a time, nothing worked.
I did take the car over and had the battery checked, they said it was in A+ condition.
I removed the Backup Camera Fuse instead of disconnecting the Backup Camera,
just too much work to disconnect the camera, still didn't work.
I Checked all of the Electrical Devices in the car to make sure they still worked (Power Windows, Power Door Locks, Power Sunroof, Power Mirrors, Heat, AC, Garage Door
Opener, USB, Cigarette Lighters, Cruise Control, Park Assist, Traction Control, Electronic Parking Brake, All Lights, Trunk release, etc...); everything worked except the Touchscreen/Radio Controls, CD Player, Bluetooth .
I got out my Old 2.0 HMI and Radio Module.
I tore apart the Dash and Replaced the 2.5 HMI with the 2.0 HMI and Voila, the
touchscreen worked, I'm Lucky I didn't sell the 2.0 HMI and Radio Module on Ebay.
There goes my
Car Play/
Android Auto Upgrade, as the 2.0 HMI doesn't support
Car Play/
Android Auto.
Too expensive to Replace that HMI again. last time it was almost $1000 and I
did all the work installing it (not a shop).
