Hey all! Trying to do this and it seems like we have been pulling all the wrong ones...we have pulled and reattached each of the corner ones and with 3 out of the four we got the "cal error" and then it went straight to error and didnt do anything. with one it stayed locked. we are trying to make the radio in a 2000 venture a cd player which came form a 2000 venture. any help would be appreciated! thanks!
