Thread: About 37xx converted to 34xx satellites reception accuracy

Here is the file that @isg talking about

1.) Extract rar from above link
2.) Rename in .System your GPS folder to GPS1
3.) Add GPS folder from step1 on your nuvi in .System folder
4.) Go outside, whait for satellite lock and make procedure for satellite accuracy again
5.) If all go Ok, you will have 3m - 5m accuracy

This is from EU nuvi 37xx --> 34xx with 3m accuracy beside my window i didn't test it on road, but this file test @isg

p.s.

Thank you for your time and test and for your review

I will be very surprised if it work
This ARC.BIN and BEE.BIN files is familiar from the times of the first GPS Chipset Type M HotFix on Nuvi765 (a couple of years later on 2x5 MTK). They were naturally investigated. During time of work the content of this files was constantly changing. Consequently it is the usual cache data for HotFix. Idea of HotFix is instantaneous satellites acquisition if device was ON after relatively small period of time in the same place (internal clock has no time much behind). It worked fine and I never saw at least one non-green band on GPS bar. After using SIRFIII device it was fantastic!!! Naturally I was trying to change this files by files from other device and time of satellites acquisition was a lot more.
May be if if you do substitute this files a device does not have appropriated data for making of Hot Start and it does Cold Start. Hence the temporary increase of the accuracy take place...
