1. Find a PC running Win XP OS or later [forget using Linux even with a Win VM].
2. Extract this onto a CLEAN microSD [i.e. empty]: [Only registered and activated users can see links. ]. It's made with v5.8 boot bin as ldr.bin, so it will work with your flakey 1300 [first double-check that it is definitely the non-MTK chip HWID 0972 - open the GarminDevice.xml from the unit's Garmin folder and look for <PartNumber>006-B0972-00</PartNumber> towards the start to confirm].
3. Insert the card into your nuvi 1300 and turn it on, then wait until it reboots before removing the card.
4. Check that you have 41.bin in the Garmin folder of the card and that it's not zero bytes [it should be 4096KB].
5. Copy the entire card contents to a safe place.
You only need to restore your favourites and any other personal data. Everything else with be unaffected after hard reset/clear non-vol.
