No probs Alan Z - same issues i think


Update

My situation - screen working but how and why is still mystery

What I did was... i took out fuses 71, 72 and the two green relay blocks from rear trunk and checked before replacing - no change still blank

as i drove away it suddenly displayed everything on the bordmonitor except the sat nav (in a old style blue screen format which i believe was the TV module taking over)

I tried to update the software thinking that i could at least see if the os was loading - no change still old blue screen

so i decided to put the original nav unit in and hey presto saw the bmw logo and then normal screen nav included

i havent got a clue how and why - maybe someone else may be able to shed light but it could be worth doing the fuse check?
