dasilvarsa and kanopus,

If you don't have interest in help or have some doubt, so respect the guys that want to fix or discover a thing fix accuracy be the same live original 34XX.

I'm not a noob with Garmin and GPS. So, please, believe in us. Angelozip is an expert in GPS as well.

We are not developer or programmer, but we are sure about the issue and YES, this is so much important to US.

You know São Paulo /Brazil? If not it is a big city with streets near each other and big sky scrapers. 37XX suffers to be in correct position, but you can imagine what happens with 37XX/34XX in this city.

And just to conclude: If nobody is able to fix it, thenI will return to the original 37xx and that's it.
