You are a star!

Thats exactly what I needed to see !

I`m on the case - will shout as I need more info (or units)

As an additional side line, they do have a common failue mode where the main ribbon connector for the Sharp LCD display can get dry joints with age causing poor images........not to hard to fix with the right tools.

Have a look on here:-

If you can etch one of those boards and build it up for a reasonable price, I would be very interested!!!!

Hmmmm........nice big flash chip I can see in that pic.....got a programmer for one of those at work

Yeah, I spotted that one - the only problem is that Vauxhall are renowned for fusing the data lines once they have been encrypted making reading and alterations somewhat tricky . . But not impossible.

Hot Air or Laser? I`ve not yet seen one in the flesh yet.

I use a hot air pencil set to the correct temp.

You could do it with a microscope, steady hand and fine tip (there not that fine a pitch)

I was thinking of taking it off the board.

The thing to consider is that its probably NAND flash so block read/erase and its also re-configurable via tech 2 so it must still be possible to read/erase.

My experience of the Radio side of the codes / tech2 may differ from these displays, but what I know so far. . . .

One of the other models in our research dept at the moment, The DVD90, appears to effectively load an eeprom on power up from the flash and Tech2 reads and writes to the eeprom, not the flash, but when powered off, the eeprom is emptied. The flash has multiple data lines in to allow for programming, but it is difficult to access all areas without all the data lines. The PIN code is retained inside the part of the flash memory with data lines fused. We are using a secondary chip piggybacked on the top to monitor data in and out, and its by reading this afterwards that we can get the code. A quick calculation from an algorythm we have here then gives us the PIN code from that data.

Exceptionally long winded, and so far the hardest radio code I have ever had to crack - if the CID displays are similar, then it may be a case of reading them "live" rather than chip off.
