Hi all I have a little project I'd like to do on my astra, but not sure if it is possible to do, anyway my astra is a Sri turbo 06 with cd30mp3 aux version and a bid screen.
when I unlock the car the screen turns on and radio iluminates.

I want to a a personal message when this happens instead of the day I want it to say Sri turbo for now.

so how would this be acheved I no the screen request info from radio unit and there is space for the data in the radio would it be a case of modified the jump address to display my added data or is it more complex
