The version is IG4.
I'll try to paint a better picture:
Road Runner is running with DFX loaded. Press GPS button IG4 loads and looks good. Press gas button. Prices are not loaded automatically, so I press 'Reload Prices'. Prices load for the ZIP code. Since installing the patch; after a short delay IG4 screens pop up and the coordinates automatically enter. My new route is displayed (at this point everything seems good). I then press the anti-'Route' button, which is 4th down on the left of the default screen, and... Crap... it worked, the route dissapeared (it figures).
Ok, again, I press gas and choose a gas station and press 'map it', a new route loads again. Press the anti-route button and the route does not clear. At this point I can't pan the screen (I get beeps). I can't even press the menu button (more beeps). It's like the route button locks things up. I then have to go to menu and back, then route still doesn't work. but it doesn't lock me from being able to press menu>>destination options>>clear route.
In addition, if I select menu>>shortcuts>> go home (I set my home already), the route loads. Pressing anti-'route' button now does not clear the route, and an IG4 'Current Location' window pops up. (This is what I was getting before with map-it). Menu>>destination>>clear route, works in this instance.
I'm sorry it's really hard to specify the problem, because the problem isn't very specific.
Does that make more sense?
