Today I received a prestine second hand nuvi 3790 to play with, It's my intention to flash one of them with the 34xx firmware.
Before I do that I want to know what updates the 3790 dashboard on S/W v5.00

originally I thought this was done by the Garmin webupdater app ,but doesn't appear to be the case?

Both devices under "about" apart from Unit ID obviously share the same information, as follows....

Model nuvi 3790
Unit ID: **********
Software version 5.00
Audio version 2.50 British Emily
Text Version 3.10 British English
GPS Firmware 2.60
Bluetooth Firmware 3.0.35 P55
PMIC Version 824
TSC Version 1.23

The only mod I did was on the older device, which came from TSC version 1.16 to 1.23, but that obviously bares no relation to the dashboard anyway.
Both dashboards are totally different,
My original unit has the dashboard to the right of the screen, while my other has the older style dashboard which is a bar at the bottom of the screen which allows the map to be viewed more.
Anyone here know how to change dashboards in the 37xx series?
Thanks.
