I have a 2000 Kamberra and have recently started having problems with my speedo and Tach. They have become intermittent, actually more off than on. I was told the Black Box might be the problem. I understand that the Black Box manufacturer is covering these because there were lots of issues with them. Who can I contact to get a new box, it looks pretty easy to install so I would prefer to not have to go to the dealer for a 10 minute intall.

Thanks
