[sjc1]

I need to change a dash unit on a 2003 corsa c but opcom wont read the eeprom or security code any help appriciated.

You can post VIN maybe i or someone can help... or if you have carprog then you can get pincode from ecu... or you can get pincode from aerial reading tms... what happend with the old one? if the car runs without it then you can put the new one and will do the same then...

bad clone of op-com my read all the time no problem, if you need pincode read tms and post dump here..

[sjc1]

i can get code from current one by reading ecu but the donor unit i cant. the current dash loses can comms and stops the car starting
what versionof opcom should be abletoread it?

If the hw is the same try to save eeprom with opcom from old dash and save to new. If I remember you need to keep reset button depressed while writing.
