Hi man
I don't find any way to put the system in pre-boot .
I have only the splash screen GARMIN.
In my Radio there are a few sequence with buttons and reset but it's only for test mode or pre-boot of the radio system
I already tested all the sequence in particular FUNCTION + EJECT + reset put the radio in test mode but nothing change
So I think no way to put the garmin unit in pre-boot.
Yes already using in my test updater and right rgn to recover "System Software Missing"
So I start to dissasemble the unit
Before to start any other idea to test any other software ?
Thank's
Ok
it's right .....
this time I'm at work and it's impossible to disassemble .........
Thank's
Best Regards
If you have system software missing on screen then you already in pre boot mode.
Conect radio and Pc and run updater.exe and updater will see your radio with serial 0, if i think that updater will see like "Device 0"
You must flash with updater + .rgn, gcd wont work and also wont work flash over SD card.
Hi
no I don't have the SYSTEM SOFTWARE MISSING
only a screen with logo GARMIN
Other time i tested different firmware and arrive SYSTEM SOFTWARE MISSING
connect usb and restart with correct firmware.
This time don't arrive this but only a fixed screen with in the center write GARMIN
If you publish photo of navigation system board, I can mark testpoint pin for get into pre-boot mode.
Thank you
this week end I dissasemble the unit and post the photo of the board inside the radio system .
Now I am at work and is impossible to do .
So I must extract the radio from the car and then disassemble .
