Go 300 wont recognize SD card or even ask to format is and resetting doesn't help. I have read every help article I can find on the internet and nothing works. I made sure my card is compatible, formatted it as FAT 32, treid resetting the device the the reset hole and also "holding down the power button for 20 seconds till you hear a drumroll" which I never heard. I can't get past the screen asking for a card and when insert one it rejects it and I can't get it to format it or even ask to format it.

If the serial number of your GO 300 starts with "M1" then TomTom have declared that device as "End of Life" see https://www.tomtom.com/en_us/obsolete-products/
That means there will be no more maps updates available
