I've got a CD70 NAV thingy with the colour screen. I read somewhere on here that holding down "settings" would allow you to see things like the engine temperature.
Now i've held down settings, and it beeps (similar to the beep that you get when told to fasten your seatbelt on a plane) and states that testmode is on / testmode off, depending on whether it was on or not before.
But i've no idea what to do / what you can do in this test mode. Can anyone give me a heads up as to what i can do in this mode?
I've no real reason to be messing about in this menu, I'm just a nosey bugger!
