well the installation went fine (many thanks to the ASR removal/refit download from their sight, cheers guys, very easy to follow).
I didnt experience any problems, except for how to work out how to get the arial to go up and down, at this stage it is just stuck in the down position, but the radio still gets reception which is good. Dont know about out in the sticks though??
I took the opportunity while i was there to pull out the trip meter switches as the up button wasnt working. Pulled it apart and put it back together and stuff me it is now working??!! guess i saved myself a hundred bucks from getting it fixed by the local holden ripoff, oh i mean dealer!
Have put some pics for you to check out how i went and how it all looks now...
