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.

Have you noticed any giant, white balloons floating overhead at the same time your Nav stops working?
Seriously though, have you contacted the Dealer to see if there are any recalls for your Blazer? They may be able to shed some light on it.

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"
Unfortunately, it seems that most of these problems occurred in the 2019-2020 Blazers. I know there have been some issues here and there with 2021s and up, but I see that most issues are in those first two years. I've, other than waiting on seat chips and having the harness for the auto-dim mirror on the driver's side missing on delivery, had zero issues with my 2022. I remember when I got my Blazer back in January 2022, I looked up any recalls on it and it revealed hundreds of recalls in the first two years of this vehicle. I was blown away. Anyway, I hope the OP can get their gremlins fixed without spending too much money.key words "should be"
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 .
