I have the 3790 and I find that often when I push the input screen and get the little "Beep" feedback, that sometimes it is loud and other times it is not so loud. Sounds sort of muffled.
Anyone else experience this ? I seem to recall the same sort of thing with a couple other Nuvi units I had.
Just wondering if I have a defective unit or is it fairly normal.
Is the difference happen when you have the unit powered through the mount verses when you have it running off the mount on battery?
The volume will be loader when you have the unit in the powered through the mount as there is an additional speaker in the mounting piece itself.
There is a difference regardless of how I am powering the device.
On battery power, there is still a change in sound volume, and I experience the same change in volume levels when I am plugged in.
Haven't notice that issue on my 3790.
Thanks. Sounds like a candidate for a return to the store.
Haven't notice that on my 3790lmt either.
Yep... sounds like I managed to get the one defective one out of the hundred units they have in stock.
I won't be buying a lottery ticket this week with that kind of luck.
Is it possible that the way you are holding the device may be blocking the speaker? It is easy to do on the 37xx series. I have the 3760 and have to be cognizant in the way I hold it to avoid this.
Just a thought.
Good point, it is easy to put your fingers over the speaker holes when you hold the 3790, especially if you have it in horizontal mode. Another reason to use Portrait mode I guess.
But the unit was in the mount and I wasn't holding it at all. Just pressing the screen.
It could also be that the 12V connector was not fully engaged into the cig lighter socket and the unit was inadvertently running on battery power. This happened to me. The unit will not power the base and the base will muffle the speaker. My volume was low and that is how I noticed that my unit was slightly unplugged from the power when I pushed on the connector and the light came on. It worked fine once the 12V was reestablished.
I disconnected it from the power cable, left it in the cradle and it acted the same flakey way. I removed from the cradle and it was still acting werid with two differing volume levels at intermittent and sporadic times.
I did notice that the volume automatically drops lower while powered on battery. Try checking your settings power management settings. Other than that, I am out of ideas for now.
Thanks for all the suggestions. I've gone thru all the scenerios and the results do nto change.
It's going back to the store for an exchange this week.
I'll let you know how the new one is.
Please do. Hope you get a good one - I have always bought mine on line and have had good success.
My volume doesn't work at all on my 3790LTM when mounted. This is the second unit it's happened on. The first one I took back to the store and now I have to send my second back to garmin. Now I'm wondering if I'll have the same problem with my third.
I got another 3790LMT and this one seems to function better then the first as far as the volume goes. It's pretty consistant volume and does not sound "muffled".
The old unit had actually gotten worse. The volume for everything on it had gone down dramatically.
But the screen brightness on the old unit was higher/brighter than on the new unit.
I wish they had some consistancy in the production.
Now that the "new" nuvi series has been announced (3490LMT) I have to decide if I keep this either or just spring for the extra and get a 3490.
I don't see the volume issue but can't get the buttons to detect a touch sometimes. I touch it two or three times before it "takes". I don't have fat fingers or anything. My iPhone and iPad work just fine so I don't think it's me...
I thought it was just me.
I find the touch screen does not always register my touch either.
I sometimes have to touch it 3-4 times for it to react.
It should be somewhere in tools I believe.
The 37xx series has no means to calibrate/recalibrate it's touchscreen because it has a glass capacitive touchscreen.
