Downgrade firmware?

Does anyone have an old firmware version I can download? I'm looking to downgrade to 70.00.352 NA. The new firmware 74 version has some car play issues that I didn't have before.

In my experience with Android Auto, I believe that sometimes it is updates to Android Auto and/or my phone that cause problems for one to many weeks until they quietly get resolved with future updates.

It may be coincidence that the problems are occurring after your update (assuming they weren't immediate).
