2. I have also never see this happen before either. In fact a lot of the stuff that is happening on your system, (Weather maps now showing up, iG Auto Switch not working ect) I have never seen before
3. Ok, I read, re-read, and re-read that over and over, and am as confused as when I first read it hehehehe. What really threw me off is " it seems that a better approach would be to place a button on the XM skin that brings up the XM player skin". There is only one XM skin.... So when you are in the XM screen, you want to go to the XM screen? Sorry, I am just not following you here.
I did make one alteration however. When in XM and go back to the main menu, and press music, the browser screen came up, and XM would continue playing. For RR to know to stop the XM, the Player screen needs to be loaded. I noticed this in the car the other day. I changed the button on the main menu screen, to now access the player screen.
