Hi ccfj1,

I got the disc through, thanks for that. very kind of you.
Unfortunately it hasn't worked.
I followed the instructions religiously, and have tried a number of times, grr.....

The drive is reading the disc, i can hear it spinning up etc... but when i turn the ignition to the first turn, the screen instantly displays the Blue screen date...

I guess my only option is to either get this unit replaced, or send it off for repair somewhere..

Although.....

I heard something about unplugging the unit for ten minutes and then reconnecting and trying to flash the drive again, is this worth me trying? or should i just face that i have broken this unit?..... I have disconnected the battery for five minutes, which didn't work, just reset all the clocks and tripometer.

No, I don't think this will work, the rom is corrupted and as such no amount for unplugging will fix it, the rom requires a reload.

John how do you reload the ROM mate?

Take a good Mk4, unsolder ROM, copy with ROM reader

Take bad Mk4, unsolder ROM, program with ROM writer

Resolder ROMs in both Mk4s

lol, Jochen beat me to it Stan,

The only other ways are good OS via cd, or rom reload on the bench with the mk4 connected to a PC/diagnostic unit.

Or sent to VDO repair in Wetzlar Germany

Mk IV sat-nav same problems

Guys

I appreciate this is a fairly old post but after searching for an answer to my current problem I seem to of stumbled upon the answer. Mine is a similar problem to the blue screen in the pictures, however after a short while the sat-nav unit re-boots and ever thing seem ok for a while. Then it decides to just keep freezing and resetting itself. I've up graded from v31 to v32 and then back again but nothing seem to work. do I assume I also need to buy a new Mk IV sat-nav unit.

Thanks in advance:bustingup
