My navigation has been acting up lately. One day it's working and functioning, then the next day it doesn't work at all. I called ONSTAR, and they advised me to reset the SD card. It didn't work, any suggestions or has anyone been able to resolve this issue.

Thanks for the reply ,I will try this today.
Unfortunately , powering down did not work so i called Onstar again to cancel my membership or fixed . this time a real tech run a diag for about 15 minutes and find out that something wrong with the hardware and advise me to take it to dealer free of charge .
