Hi everybody, sorry for my bad english,
No, but not sure how this could impact the situation here.
Actually, re-patch is indeed not necessary.Try uninstalling Android Auto in the Play Store removing the updates. Then run it, letting it update.
I was running AA version 7.0.614134 and it the apps stopped appearing. I uninstalled AA and it updated back to 614134 and the apps reappeared. I did not have to re-patch.
Nope. Unfortunatelly that didn't work for me...
