Hello, I have exacly the same problem.

I own a european AVIC F900 unit. For one year, no problem. And on day, a black screen after startup, and then nothing. Just black screen.

After some testing, when keeping the map button pushed, the screen comes back.

I recently decided to go for the 2.009 european update. The update went fine.

But now, when I am trying to go on the MAP section, I can't go in. Eventually, it reboots.

Finally, I have checked the version. It says : no map version.

Somebody help please... ? Thanks.

Thanks a lot, it worked !!! I just don't understand why ? The parking brake wire is supposed to send some low voltage stream when the parking brake is on. That way, the unit knows PB is turned on, and allow you to watch TV. So why grounding the parking brake cable included in the unit F900 would "simulate" a low voltage stream ?

Anyway, thanks again !

Hello everyone. I am in Europe and have a AVIC F900BT (european model).

I understand everything, I did the software bypass without any problem.

The only problem I've got is this : Can someone explain practically how to ground the parking brake ?

Here is how I did it : In my car, there is a cable starting from the parking brake. I attached to this cable the one from my F900 unit in order to watch DVD while the parking brake is on. And everything is ok.

Now, in order to ground the parking brake wire, I attached a cable from the ground wire (black) of my F900 unit, to the parking brake wire. In consequence, my parking brake has now two cables attached to it.

The result I get is now : whether I drive or not, impossible to watch a movie, I always receive the message that I can not watch TV while driving.

Did I do something wrong ? Maybe, since there are two cables attached to the PB wire, one must be bofre the other ???

Any help is welcome, thanks !
