Thread: Transform a Nuvi 37xx in a Nuvi 34xx for dummies

There are whole threads in Noeman and elsewhere devoted to problems experienced by some users due to satellite accuracy problems after conversion. In some cases minor and dismissible, as found by both myself and Kanopus with our converts, but there are many more reports of accuracy loss severe enough to be concerning. Perhaps that's because the ones not having such problems aren't reporting it, and the others are. Read this thread: [Only registered and activated users can see links. ] and then decide for yourself. It's now very easy for novices to convert and reconvert using the sd method. Heed the advice about NV backup and you won't risk anything. If unhappy you can always come back to 3790. Apart from the 34xx features already mentioned, such as Guidance 3 navigation, there's Android Smartphone link, and you can enable extras such as Video & mp3 players, so you may wish to read this thread also: [Only registered and activated users can see links. ].

Thanks for the info. I've tried flashing over 7.10 34xx and was successful. Reading the 1st post, copying over all xml files over to the Garmin directory will enable all features if I have 7.10 and older versions. I restarted the nuvi and the features in the Apps folder don't show up, what have I missed here? I'm not really sure if the xml files won't work in 7.10 because it is said in the first paragraph in the green note in the OP that "since sw 7.10" it is not supported but in the second paragraph it says "If you flashed the old firmware 7.10". The first paragraph means 7.10 does not support those xml files but the second paragraph says it does, so which is which?

EDIT: Nevermind, I tried downgrading to 7.00 and it still didn't work and then I tried 6.20 and the xml copy method worked just fine, I have all the features enabled now. This means that since 7.00 (not 7.10) the enable features application is not working.
