Verizon Galaxy S7 NOT working with Android Auto ...

Just to update this thread...

After trying many different cable combinations, multiple settings changes, uninstalling and reinstalling apps, I am happy to report SUCCESS!!!!

Wife's OEM cable with developer options turned on, usb debugging on, buffer size for logging set to 16 MB (Don't know if this did anything, but someone on another thread suggested it so I went with it), usb configuration set to mtp and we are rocking and rolling!

Thanks to everyone who tried to help. This truely is a great community.
