2016 Chrysler Town and Country RHB

Postby Draiter » Thu Jul 17, 2025 1:06 am

Hey everyone.
First post here
I have an RHB radio in my T&C.
I was able to add the US 2026.10 map using gmapsupp.img
I then named the Canada and Mexico map gmapsupp1.img
The US map flashed fine, but the canadian map wouldn't flash. I then changed the Canada map to gmapsupp.img and it doesn't detect it as a supplimental map.
I have the file structure e:\garmin\gmapsupp.img on a fat32 formated usb
Can anyone please help me? Right now it appears as tho the original map is gone... I have no canadian navigation.
Thanks

Welcome to the forum, have a look in your garmindevice.xml there might not be an option for a second supplemental map, only gmapsupp.img and gmapprom.img.

Hey, thanks for reply.
I searched through the garmindevice.xml and there is no mention of supplemental maps only base maps... but the system picks up the gmapsupp.img file.
Any ideas?

@Draiter
no need to create another thread.
Not an easy task to find old maps as the have long gone past their use.
Are you trying have North America as 1 file ?
You can make a custom mapset using Mapsource under the 4Gb file size limit from the current version without Mexico and other selected areas you are unlikely to drive to in your own car, Alaska & Hawaii for example.

Hi again,
Sorry for the new thread....
Every time I try to update to a new map I get this warning saying the map is not compatible... I am on software vers 6.22.
So I am at a loss as to what to try next...
I do appreciate the help.
