I have a 2009 Honda Crv with integral Sat nav / Media player.. The Sat nav mostly works fine with the occasional exception when it refuses to recognise the GPS receiver and puts me in the middle of Paris..

That said, about two months ago a Pop up window appeared in the middle of the screen and refuses to budge. The sat Nav works around it, the map shows beneath it and the keyboard functions beneath it.. the problem is that over a third of the map or keyboard are obscured.
