Just wondering if there is a better place to stick the aerial rather than on the heated windscreen, just in case the heated element interferes with the signal??

If you stick it right at the very edge on the passenger side, the elements don't go right to the edge of the screen. I fitted it there on our 4.0SE and it only drops out in the same places as mine (in a dip surrounded by stone houses next to where the step daughter works) with an amplified whip aerial on the roof.

Thanks Richard. Good to know. I’ll crack on 👍

I tried various screen antennas with little success. Even outside the heated area, I suspect the glass tint is not helping.

Now both my P38's have magnetic roof antennas which work really well. Eightwood DAB Antenna

That's similar to what I have on mine but with an external 20dB gain pre-amp. The signal still drops out in places, notably the M11 between Duxford and Stansted, but works well in most other areas. I expected the screen aerial to be pretty poor when I put it on the SE but as it came with the head unit I figured I might as well give it a try and it works far better than I thought it would.
