Thread: How to install any Garmin map on Iphone Garmin StreetPilot

I'm stumped--does anyone know how or what file the Garmin 2.2 app references when pulling POIs? And before anyone says "Google Local Search" or the SID file--I removed the SID file from the SID folder, and put my iPhone in Airplane Mode...yet when I do a POI search for say, Food, it lists a bunch of restaurants near my current location. Are the POIs buried within the gmapprom.img file itself? I don't see any other file in the Garmin app folder large enough that would contain POIs for the entire USA but not be a file for some other clearcut purpose.

So I guess the Garmin iPhone app doesn't make use of the SID file after all--in which case, that's 324 MB of space I can reclaim on my iPhone; that, or else the SID file I installed on my iPhone is corrupt...but if that were the case, then POI searches would not work at all--yet clearly Garmin is able to search for and display POIs.
