About 37xx converted to 34xx satellites reception accuracy

**giuseppe66** · 20th February 2013, 05:06 PM

1) in nuvi 34xx with poor accuracy i've do a copy of all my folder and files on my pc, then i've delete all folders and files not important from nuvi;
2) flash back it to 37xx follow Caty's guide and files [Only registered and activated users can see links. ]

3) i've turn on and test accuracy of 37xx with essential files (no map, text, asr, jcv....) and i've good accuracy;
4) then i've flash to 34xx again with firmware 3.50;
5) Caty's solution "convert 37xx34xx.zip" and then Lolypop000's solution "region 139...";
6) backup on pc of "clean folder and files", share on post up;
7) test the accuracy with 3.5 firmware and it's good, like 37xx for me;
7) update with webupdater to firmware 7.6 and other files (voice, asr....);
8) test accuracy and it's good, like firmware 3.5;
9) update with my lifetime, map, asr, jcv.....
10 ) test accuracy like yuo can see in my picture in post up.

For me of course, i've not never see good accuracy on my 37>34 and now yes. Blu bars don't go up and down like "crazy" but now are enaught stable
I don't now exactly if there was a problem with firmware (i've use firmware 7.1 first time i've convert) or a problem with files because i've clean nuvi before flash to 37xx

Hi, Thanks for the tutorial!

But I'm not understand some steps:

4) then i've flash to 34xx again with firmware 3.50;
5) Caty's solution "convert 37xx34xx.zip"

Twice? Did you tried to convert 2 times?

Now I'm with 37XX, so I have to flash 34XX firmware 3.50 and after that "convert 37xx34xx.zip" from here:

"Another way to convert 34xx with logo and enable features :

Flash full 34xx firmware
Unpack the file to an empty SD card, turn nuvi off, insert card, turn nuvi on.
remove sd

and to return to 37xx ,its logo included:
Flash full 37xx firmware
same as above,unpack the file to an empty SD card, turn nuvi off, insert card, turn nuvi on.
remove sd

Download: Udated on 13.10.2012
added Video Player and Premium Point Addressing and updated Ldr.bin"
