What ho one and all,
For years, I have had an unresolved issue with my head unit. Went over a bump and it went off. One way or another, I found that thumping the driver door card speaker area, and it would come back to life. But it progressed until it would not come back, but there was an electrical static discharge sound through the speakers. I posted questions here, but to no avail; I got a replacement from a breakers and that did not work; I changed mine with a neighbours and his worked in mine car and mine worked in his, but mine did not work in mine.
So have not had a radio and had to make conversation with SWMBO. But sometimes, go voer a bump, or thump the speaker, electrical discharge, the hu goes off, and when it lights up again, it is working just fine.
Because of the OSF thump test, I figure there is a wiring / speaker issue inside the door, but replacement speaker and checking the wiring ans still no solution. But recently it has started to work, so happy bunnies all round.
Until yesterday!!!! The radio was working, and I had to do something in the rear; I closed the drivers door and the hu went off. But to add a new twist, the display was totally blank, dead and the On/Off button did not change anything.
Today, I checked the two fuses F69 and F72. All fine. But when I replaced F72, Vehicle ID appeared on the screen but pressing any button is not producing any numbers. And pressing On/Off will not turn the hu off either. Furthermore, there is this strange 'heartbeat' from the NS speakers only.

To turn the display and heartbeat off, I have had to pull the hu quadlock; reinsert it and the heartbeat and display is blank. Hit the On/Off, Vehicle ID and heartbeat reappear, but the On/Off again, will not turn it off.
So I am at a complete loss. Can anyone throw any light on this (I'm going to guess the answer is No) But I don;t know where to check as everything seems to be working, just not in the way it is intended to.
Toodle pip and thanks
