WOW !!
After charging for severak hours, the 3790T powerd up again !
However, it now says 37xx instead of 3790. After a malfunctioning map update, this state came up and Cathy helped me to run a procedure to restore its original properties.
I will try to find the files and run it again, to fix this.
Thanks !
Did not work.
I have the original files, copyied them to a clean SD, but the nuvi does not boot from the SD.
