My original DMS disk died (20g) replaced with a 40g, can't hack Mazda

It looks like you can't hack the car radio without the original DMS - which just died.
How can I proceed from this awkward position?

Respectfully,

Either have a look on Ebay, or find someone near you that is able to hack kegs or willing to send you their DMS.

It might be worth letting us know where you are in the world.
