I've been trying to get IGO8 working on my Magellan 1424 but I have some problems..
First - the GPS does not have a SD slot so I need to get IGO working on the internal memory.
I've followed suggestions from your board and others to try replacing Navigator.exe with IGO (renaming) - no luck. I then downloaded Softbutton and tried that with some success.
My problem is that I can get IGO running using softbutton however the Mgnshell (with the second startup screen) stays in the foreground and the only way to get IGO up front is to use softbutton to kill the mgnshell program. Then IGO works fine until I shut it down.
While I've seen this issue discussed I haven't seen a solution. Does anyone have a solution that will either force mgnshell to the background or allow me to kill it without having to do it manually everytime?
