Since you got this far i assume you have the skin up and working fine, and you just need to configure your gps app settings.
1. Skinbedder nolonger is being used by this skin, although the dir are still in lstools and things do still point to them the actual .exe for skinbedder isnt used. So dont delete anything out of lstools.
2. Setup your GPS path in RRConfig.exe to
change the window name from skinbedder to iGuidance
GPS Mode is External
3. in RR.ini add this line
Run RR, click and hold on the existing NAVI button, a command list screen should pop up. Choose IG3. The button will still be named NAVI
you should now be done and working.
