I've got a problem, I was trying to dail in the speedometer using the +,- buttons for the dual analog speedometer and before reaching the actual speed, the thing pegged out and pushing the + button does not affect the needle on the speedometer any more. If I push the - buttion the needle will go back down but I can not get the needle to go up enough to match the actual speed... anyone have any ideas for this?? btw it is the pre-millenium dash.
