Thread: How to make Google Local Search/Weather/Traffic to work on Garmin StreetPilot 2.2 for iPhone

Okay so I learned from reading in this forum that GMA is Garmin's authentication protection scheme; as for the UNL files I suppose I could use JetMouse on locked NA and 3D IMG files to generate the UNL files but not sure how to generate the GMA files. If I had to guess, I think the newer/recent versions of the Garmin app for iOS are coded so that it will only recognize maps that have GMA protection scheme--this may explain why I get prompted to d/l maps even though I have replaced the original (locked) maps with unlocked maps loaded in the same locations as the locked ones originally downloaded via the app...the app is unable to find the corresponding GMA and UNL files associated with those custom (unlocked) maps.

So...is there a way to manually generate the GMA files on a locked map/img? I'm guessing the answer to this is "no"...
