2019 Landcruiser 200 Map update Bricked System

[adamjedgar]

Hi guys, 

our local toyota dealership for the last 12 months have tried at least 4 times to update the navigation maps on our car.

I have repeated warned them that they need to be careful which SD Card update they try to use, however, they have ignored my warnings and a month ago, they appear to have completely "bricked" the system. The maps screen is now completely blank and it says to contact toyota dealership for help.

The dealership have no idea what to do now and have informed me that a warranty claim has been submitted to completely replace the map display unit.

 

My wife is just a little ****ty right now as she has been without a functioning maps display for about 4 months in total and now this.

 

So, given the unit is going to be replaced at some point, i have decided "what the heck, I may as well try to find an SD Card with a firmware update that can "downgrade" the ******up the dealership have caused".

 

Does anyone know if its possible to "unbrick" this system with an older firmware update (say the original 2019 one)?

 

Any ideas/help would be appreciated.

 

kind regards

Adam

Adam, reality is whilst it is handy to have an onboard GPS unit working, we have resorted to

using Google Maps on the phone. It is accurate and always up to date. WAZE is also another

App if you're into that.
