That TESTMODE.KEY didn't work either. Same problem.

Thanks. Will try this today and get back to you.

I am unable to enter testmode. I have an avic-mrz099w. I put the testmode.key file on an sd card and the unit started on the screen it says CAUTION! TEST MODE FAILED STARTING [Turn Off ACC] I've attached a photo of the screen. The unit is on my bench and I only have the power cables connected. I don't know what the other connectors are for. I have red & yellow connected to 12v and black to -ve. Can anyone help me with what I have to do. Thanks Robyn
