This thread is way out of date, but the trick to running at least iGuidance 3 is to use GPSGate and run a virtual Com port 2 - GPSGate will get the info on 4 and share it out to other programs on com2. There are some techical reasons for this, and if you search this site you will find the answers. For those that are having issues with iGuidance 3 with the update and it is not working smooth and not updating while you drive this is your issue. As to not starting do a search for AstroGPSLauncher - there is also a Mortscript setup to launch GPSGate, AstroGPSLauncher and then iGuidance while resetting your power and backlight settings. iGuidance does not know how to "turn on " the GPS hence until you run Googlemaps or someother program it won't work. Funny thing is GPSGate won't do it either so AstroGPSLauncher is what you need. I've tried iGuidance 4, but the voice prompts jumped at the start and it wouldn't say the street names and my phone stops working while its running - in iGuidance 3 with the update none of these are issues.
