My nuvi 1300 with part no. 006-B0972-00 seems incompatible with 6.2. I downloaded it and renamed it gupdate.gcd and stored it on my sd card under the Garmin directory. With the sd card in, boot up goes into a repeating flash-reboot loop and it won't power down. At the point of beginning reboot, I can remove the sd card without damage to the sd card or its files. It then reboots normally into version 5.8 and I can power down normally as well. Is there a secret trick I don't know about to get this to work? Do I have to upgrade to intermediate versions in sequence to install 6.2 or is it just incompatible completely?
Is it possible it has something to do with my enabling of JCV and speed limit features as per tutorial on this site?
Jimmy, Thx for advice. I did exactly as you suggested but unfortunately am getting the exact same behavior. There must be some other problem.

No, it's definitely not the problem. Flashing the senior model logo to your 1300 only changes the Splash to D1340-50 from its original D1340-00. It does not involve the firmware at all, only enables the features provided by the fw which previously were blocked to the unit. All 13xx/14xx from 1300 to 1490 use exactly the same firmware. I've modified the splash to D1340-50 on numerous 1xxx which are all now running V6.20, including a US 1300 identical to yours.
Do as jimmy suggests and remove any old gupdate.gcd file from the unit's .System folder if present, and redownload the v6.2 gcd as the other file may be corrupt. You could also do the upgrade by connecting to WebUpdater or GarminExpress. Before you again attempt to upgrade, backup the unit, hard reset it or clear non-vol and also back up NV memory [rgn41]: [Only registered and activated users can see links. ] before any fw update.
