I've recently wired the whole nav and TV setup, i tested it on my MK3, works great, nothings wrong...

so i put my new MKIV in, works great too.. for 1day...

but just then, i was going back to my car to pick up something i left there earlier today and noticed that the Monitor is NOT turning on (don't even have back light). (radio still runs).

so i sat in the car, put my key in, turn on the car, still nothing on the screen, only after about 20secs, the screen turns on directly showing the nav mode (so skipped the splash screen). all function works (TV / Nav / OBC / radio / cd changer) first i thought everything seem ok at this point, but later realise the radio power bottom is not lighting up....

this is weird~~~

i pull the key out, locked the car try again, same thing happened.

-------------------------------

at this point i want to swith back to my MKiii to see if that does the same thing, but my MKIV wouldn't turn it self off!!!!

i locked everything except having the trunk open, the MKIV light was solid then start flashing (9 flashes) then solid then flashing

... normally it should turn itself off in about 1 min, but i waited and waited.. no sign of it self going into the shut off mode...

do the Ibus give signal to the nav to turn off? i am thinking maybe i stuff up the wire splicing when i did my ibus cable.... (i used the BMW splicing connector btw)
