hello, first post from a happy BMW convert
Recently purchased a 2003 E53 3.0i and have had a LPG conversion.  Very pleased with the result and love the car but I have an intermittent fault with the nav screen. Sometimes on start up it is black and flashes from time to time.
The radio still plays, but no navigation facility. The problem seems to resolve itself after 20 minutes or so.
Would appreciate any feedback on above.
Thanks

Morning and

Take a look at thisthread for starters.

Thanks Sanj for the link. I will attempt the operation this weekend. Could do with a nimble fingered daughter but they are all busy with children!
Cheers
