My Toyota Avensis 2.2 D-4D T180 5dr has a B9010 Navigation System. Recently, it had a flat battery due to non-usage over Christmas. I got it jump started after which, the Navigation system and the Radio does not turn on. The navigation system takes a Map DVD Navigation Disc that is in working condition. I went through this forum for similar topics and was advised the following:
1. Unplug the negative on the battery for a few minutes. Apply the brakes a few times to discharge. Plug the negative back on and turn on ignition
2. Unplug the positive on the battery. Leave it overnight. Plug it back in and turn on ignition
3. Unplug both positive and negative on the battery. Leave it for a few hours. Plug them back on and turn on ignition
None of the above worked. I even got an after market navigation update dvd and a new battery. I doubt that these will help me.
Any other options you can suggest without breaking the bank??
