for those who don't believe. I am on 4.20.30 and my clock was set fine at 2:28. I loaded garmin, and then closed it out and my clock is not set for 8:00 pm. So yes, you can get 4.20.30 to work as long as you are ok with your clock changing. I don't use the GPS often so I don't really care too much and I am messing with other stuff. some time I will load it up again with the older load. And yes there are 212 posts but I read them all. I guess it just depends on how serious one is about getting the app to work. Almost every question I had I found the answers to within this thread and also found how how I can find the stuff that I can't find in this thread.
