This is a great unit but two frustrations that I could do with some tips on fixing. Mine is installed in an Alfa Giulietta. Does it have to be installed so that it only powers on with the ignition? I ask because the boot time until navigation is ready is slow. Is there any way of enabling faster boot/sleep mode like on a PC?

 

A minor similar irritation, is there any way to get rid of the nag screens which have to be pressed every time the system reboots?
