Trying to update my maps in Wrangler on the old 430n device.

[Login or Register to remove this advertisement]

I was able to get the update to 7.09 on the Garmin app.

However, I have tried the 2024.20 and 2025.10 gmapsupp trimmed to <2gb with no luck. In both cases it gave an error saying that these maps were not supported for this device.

(I live in Canada, and am looking for at least a Canadian map)

Any thoughts on what I need to make the update successful? Id like to get the most up to date maps possible if I could.
