Mondo:

All my dongles will run the MCA system..

But to upgrade an MCA dongle you had to have an Assurance contract, or pay five times as much for the update as you had to for the same MC soft version update. 

When MC 3 was introduced, of the 4 upgrade options available 3 had in effect "will not work for updating MCA" in bright red on them. The forth  and most expensive option was the only one for updating the MC system with an original MCA dongle.

Sure all MC soft and MCA dongles will work with Adrenalines.

 I think all that's referring to is the software version, not whether it will upgrade the dongle or not. You simply had to upgrade the dongle and download the CPR 3.01 version (for adrenaline and mojo "classic")... my guess anyway.

I can see by the wording it is confusing though... perhaps Marianna could clarify so users are sure of what will and won't work?
