Thread: Garmin Nuvi 66 no USB detect

Hello,
my Garmin Nuvi66LM has been serving me faithfully for several consecutive years, i have been Updating 5 times through garmin express without a problem, but this week when i plugged it into my computer - it did not recognize itself as usual .
The display shows the animation as though it were connected to the computer, but the computer does not see it / not in device mamager , it doesn't even make TA-DA sound / USB DEVICE PLUGED. i tried with 4 different cables and 3 computers the same .
I tried changing the setting MTP - Auto / MASS Storage - but the computer does not see it again .
I removed the battery in 30 minutes, to no avail .
Work and navigate properly, how to do a software reset, and is there a way to backup at favorite places without a computer, through a memory card - so far I have not put inside.
Any suggestions and ideas on how to revive it for an update.
I have paid updates, but the device is no longer warranted.
