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.

the only thing I've noticed is if I treat the radio and Nav like a desktop PC it will work fine...just make sure you don't shut the engine down while radio is powered up...get in the habit of doing that and powering up your radio only after the vehicle is started.....i haven't had any problems since started doing this
I've never powered my radio down before I shut the engine off. No issues. That should be a non issue. Just like turning your AC off before powering down. It hurts nothing for your vehicle to power on with the AC turned on. Back in the day, it used to put extra drain on the compressor to do that, but these compressors today don't have an issue with that. Same with radio. It should be a non issue having it set to on when you start the vehicle. I would take it to a Dealer, or just call them, and see if there are any active recalls on it. Outside of that, someone will need to diag it and find out what's up.
key words "should be" :)
all you can do is try...good luck with your fix
