s80 satnav
 

Hope someone can help, just got myself an S80 Premium Design R drivE 2009/10 and I love it, the issue I'm having is regarding the satnav screen, only when car first starts up and I press the enter on the joystick sometimes not every time the screen pops up comes to life and I don't get very far until it switches itself off and lowers itself down, their is a disc in the unit in the boot, I was wondering if anyone had any answers, could it be it simply needs an update, would this cause this to happen? Cheers for any help

itsfar better when you use the remote control
