Ok. Thank you for your sugestions.
I have newer units that work with NT maps, so i would like to try that Goldwing patch on the Quest or the StreetPilot.
The question now is how to put the Goldwing patch on the units since you dont have access to the files, as we do with newer units. So, how to upload the Goldwing patch on the Quest or the StreetPilot?
