First of all I'm sorry if this has been talked about before, but after searching a lot I couldn't resolve the problem.
I currently have a 2004 Astra H 1.7cdti 74Kw and I'm in a kind of a struggle due to my board computer functions.
I have a aftermarket pioneer radio (DMH-A240BT)...
Im planning to do my smd conversion this weekend,
few questions i have are-
when i take the speedo off and then re connect would i have to reprogram it etc
same for the BID screen...will that need re peogramming too?
