I have a 2011 Corsa 1.3 CDTI Excite. It has a the larger GID on the CD30 Stereo.
On the display, it has two tabs, one for the radio and the other for the mobile phone.
Having read about Tech 2 and Vaux-Com, and already having the clone software, I decided to have a look.
I found and changed to value for the Board Computer from not present to present, and this then gave me a third tab on the GID, but this only showed some form of timer.
Is there another option I need to set to enable the BC1/BC2 options on the screen?
Looking at the information on the Vaux-Com screen, the Audio Index is 004 03 which I believe is correct for the Diesel.
Any advice would be appreciated.
