Hi I had car in garage for new alternator and battery and I've got it back just gone out three hours later and my radio display is on range rover logo. I re locked and now it's just the green head unit is there a setting that's been pressed?

Press the radio knob on then off
See if that helps

Otherwise remove appropriate fuse behind glovebox

Hi mate thanks for reply I think I've found what it is I'm using an AA obd charger and that is when it stays on.

So how do I work out if I drain more then I gain is the question

the display will drain more than a solar charger will gain.

You can configure the rear cigar lighters to be always active and plug a solar charger into them.
or maybe its easier to hard wire the solar charger in using a piggy back fuse.

What model is the orb charger you are using? it shouldn't cause that problem. Are you sure ?
