I have sports nav and have same problem I give it a wipe with wet wipes every now and then. Cardrossjim

If battery is below 75% charged stop/ start won't work so you won't flatten the battery when lights / heater are on and engine is not running .its a safety thing so you won't flatten the battery

I have sports nav and don't get traffic announcements even though I ticked the green arrow to confirm announcements also does anyone know how do you get warnings when speed camera is in area on your screen went thru system and ticked green arrow to confirm but nothing happens just small red triangle...
