Post # 99 was created by mistake. Sorry.
I wanted to ask which files are in the folder RXN.
On my 3790 -> 3490 there is no RXN folder.

It showed up later, I've a December 2010 3790 back up before conversion and a Feb 2011 34xx backup after conversion and no rxn folder in GPS directory is present in both of them. My actual files in rxn are dated Feb 2012.
Arc.bin, Bee.bin and mt.nvm are present in both backups.

I've do the same test today like Isg in post 103. In my 3790>3490 there was not RXN folder but only ARC.BIN BEE.BIN and MT.NVM files so i've use Lolypop000 RXN folder and then i've do the test for compare. With my only 3 files i have 6 - 10 meters accuracy and without my files and with RXN Lolypop000's folder i have 9 - 15 meters, so i (for now of course...) replace my old 3 files. Thanks to Lolypop000

Try to delete your GPS folder see post above.

I've delete GPS folder. Start nuvi, long time to see satellites and then (5 minutes about) 6 - 10 meters accuracy. In new gps folder there are 3 famous files. Then "Caty's solution" and restart. All ok, fast and 6 - 10 meters. Good for me. I replace my old GPS folder for see the differents but there is any differents. I think that my hardware use only 3 files

@giuseppe66
Despite deleting ARC.BIN etc. in my case, they appear again. What happen in your case - do you have them back?
