Thread: Nuvi 13xx and 14xx software versions summary

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.
