Hello Scott, 

Now you are testing the memory, but I recall many many years ago having a similar issue when fitting a replacement Pioneer radio cassette in our then BMW. 

In that case it was something to do with a lack of connection to ((I think) a aerial signal booster for fm. Of course, this may not apply in your case since the BMW s were not fitted with a standard radio/cassette at the time.

Having said all of that, my guess is that it's to do with a supply connection which needs to be made.  Sorry this is vague, but it may lead you in a search (on other forums?) which will solve the issue for you.

Kind regards,

Gareth.
