Thanks guys, tried it this mornig and...IT WORKS!!
Just checking, contact on and no RNS on: i see the temp and boardcomputer. As soon as i turn the RNS on, this info disappears and the temp indication, turns smaller and goes to the top of the dis. The rest of the dis is black exepct for the current street shown at the bottom and a '<W>' in the middle of the screen. This stays just like so, until i turn on the route direction, then the <W> changes into arrows etc. Is this the way it was designed??
Is there a way to check the mileage and left over fuel etc. without first having to turn of the RNS E? Can't imagine that the complete DIS is meant to be black as soon as the RNS is turned on?
Thanks again
