Two huge img files

Does anyone else have about 5GB of two IMG files on their Garmin?

I have in the 3790 system folder a
gmapprom.img 2.312.576 kb file

Then there is a MAP folder I have never seen before

City Navigator North America NT 2015.2 2.312.576 kb
and a
ac8f8cf6-0ff5-4c92-846b-2847430f3ae6.gma 3 kb

I have two previous backups for the 3790 and there is NO seperate MAP folder in them.

Nuvi 350 long gone, Nuvi 855LMT, Nuvi 2797LMT, SmartDrive 50 LMT-HD, 3790LMT now my daughters. Using Windows 10. DashCam A108C with GPS.

Nuvi 1450 won't boot past Garmin Logo

I have a 1450 that worked fine until an update. It actually worked for awhile past that so it may be unrelated but it started acting wonky with random reboots right after the update.

Now, it comes up showing GARMIN screen and goes no further. Computer doesn't see it, won't get to master reset screen and basically it is just a GARMIN 5" billboard.

Just got back from vacation in SF area... 660 GPS worked GREAT!!

Threw all sorts of wierd routes at it.. In SF, In Marin County, Greater Oakland area...
Worked like a champ!!!

Couldn't be happier with it!!

A 2689LMT in both our cars that we love... and a Nuvi 660 with Lifetime Maps that we have had literally forever.... And a 2011 Ford Escape with Nav System that is totally ignored!

Why did Garmin eliminate the ability to customize the Speed Data field on the main map?

I just picked up a 2598LMT and was surprised to discover I could not customize the speed data field. I would much rather have a directional indicator or other information to go along with the arrival time that is in the other data field (which is customizable). I'm curious why this was "hard coded" into this version of the Nuvi?

Garmin Ding Ding Sound

Anyone have the alert sound, like the one that plays at a redlight camera? The Ding Ding sound in a .mp3 or .wav? I googled it and seem to find that exact sound anywhere. Thanks for any help.

Garmin POI icon size

Is the custom Icon size still 24x24 or can i make it larger? and is there a trucker who has the truck icons I can have emailed to me? thanks.

Mapsource Co-ordinates help needed

Using mapsource, is there a way to find a co-ordinate designated as: 39.951985, -75.169531

rather than N00.00.00 W00.00.00

I cannot seem to find the right setting. I found how to do it in basecamp but I like using mapsource better.

TIA, Ted

Add Logo

First off I have a Garmin Zumo 660. I downloaded the POI file from here that has all of the Harley Davidson stores (well at least most being it's missing New Orleans HD) and it states that I download a bmp file and stick it in the same file as the GPX file and it will add the HD logo to my map when I am riding and get close to the store (as long as I am not mistaking what they are saying).

So Sad!!

I am so sad! I lost the cool breeze of the Windmill

With school starting and screaming out of control kids, I have forgotten to check the site. Will do better wink

Where I've Been? - make a route

I have the nuvi 3597, how do i convert "Where I've been?" to a route ?

United Kingdom - custom poi files


Firstly I must say this site is pretty amazing. Seen some really good things on here already.

I actually found the site because I was trying to figure out how to change my red light and speed camera alert tone to something a bit better than the current tone.

I have the cyclops pack installed (it is just the trial) and with this I still just get the tone which I am trying to change.

How well does HD traffic work in Raleigh / Durham / Chappel Hill Nc?

anyone know how well the HD traffic works in the Raleigh / Durham / Chappel Hill Nc areas?


Never argue with a pig. It makes you look foolish and it anoys the hell out of the pig!

Redlight Older Garmin Nuvi 1350T

I needed to create a custom POI and I need the red warning to indicate when arriving 1/2 mile from the location.

I created a file called;
Manually installed it to the SD card at a distance of 2640 feet.
