I have had a lot of problems with SD Cards. The car somehow destroyed a 128 GB card. Now my 64 GB card that was working fine in the car, is not being read anymore. If I check it in my computer, it works fine. Anybody else have this problem?

 

I have the following problem with my Garmin Nav SD card. It works fine in my car until I connect my Phone (Galaxy S4) to one of the USB ports. When I do that the system cannot "find" the SD card anymore.

Do you connect your Phone over USB? My car is MY2016 by the way.

 

No I don't connect my phone to the USB port, I just use BT for normal phone functions. This last time it would work for a few minutes, and then say something like it could not read the SD card. When I checked it on my computer, it worked fine.
