I found this 23 February,2011 post by Andrej. However, there were other responses indicating freeze problems using these solutions.

Cambridge 302 Compatibility?
There are two ways to use the CAI utility on Oudie:

1. Save it to the root of the microSD card and rename it to UpdateOudie.exe. Before you use Oudie for inflight navigation you will have to remove the card otherwise it will keep running the utility.

2. Overwrite the ConnectMe.exe in 2577 folder with the utility file. That will remove ConnectMe from your Oudie and the ConnectMe button will start the utility. You can get the ConnectMe back by reinstalling the firmware.
