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

I have in GPS/rxn folder this:

In eph i have 32 eph files and in folder pred also 32 pred files, but i have this also in backup of 3490 before i convert it to 37xx and before i create above procedure.
I found out that rxn_config_data change date and time when you connect nuvi to Pc, but eph and pred files in eph and pred folders have date and time when you have last time satellite signal.

p.s.
In GPS folder i only have this:

rxn and inside: eph folder, pred folder and MSL_Log.txt and rxn_config_data change date.
I don't have poly and seed folders in GPS/rxn or in eph or pred folders.
