3790 "Mixer" Volume

[mallard2]

Hi
I have two 3790t units ,on the first unit the volume is OK but the second one is quite low ( I appreciate the volume on theses units isn't the best hence the speaker mount )

On the first unit on the speaker page,I have a spanner icon to allow individual settings for navigation & phone , BUT on the second unit there isn't any spanner icon and therefore I can't adjust navigation /phone volumes independently.

It's not a major issue , but as both units have the same software , maps & individual user settings exactly the same , I am confused as to why this icon which allows separate adjustment is missing from the second unit ?

Any ideas would be appreciated
regards
mallard

I do not remember the this fact. But there are two model of Nuvi 3790 - original and predecessor (prototype) of 3490. Please check in Nuvi info the version of GPS module if it is different like x.xx vs. x.xx.xx it is mean what on the one of model is no program access to manage sound mixer on hardware.


P.S. I will check on original Nuvi 3790 then go to smoking on car parking.

Ups! Pleasant neighbor is never locking door of his car! No mixer is on his original 3790t with x.xx GPS module...
