With mapsource or if you rename current.gpx from your backup to current1.gpx and add in your nuvi in folder GPX and restart nuvi.

I'm struggling to understand the traffic trends after the 3490 conversion.
I'm of the understanding that part of the trend files is now stored in the SID folder (The G2S folder no longer being required). If that is the case, why do we still need the DB file (D317400.db) in the SQLite folder. Note, I tried deleting this file and lost the traffic trends on the installed maps section.
The confusion gets worse as D317400.db does not seem to be bundles with 2012.40 Unicode which I believe the 3490 uses?

I think logo is not a cause of problem.
(Why didnt you flash with original 34xx fw? )

Because I believe that with the original boot.ini of 3790, i.e., with the correct drivers for this hardware, it is more likely to resolve or improve accuracy of gps and this is one reason that makes me insist on this path, despite the unquestioned facilitade in flashing the firmware with the full fw of 3490 and your boot.ini, that is appropriate to another hardware (3490).

Will someone with more technical knowledge would answer one of these questions:
1. In a situation any if previously erase the Logo, we can install a firmware that is usually installed, the gps can boot?
2. If the flashing is feasible with older firmware, a old boot.ini of 3790 with modern fw_all of 3490, both with hwid mod to 1376, could result in killing the gps?

Angelo, my knowledge of fw is only basic as you know, but if original 37xx boot and 34xx fw_all gives boot loop as hwid 1101 why would an override to 1376 overcome that? Sound a bit risky maybe?
