Kenwood DMX7709s Update Boot Screen

[AlpineMatt67]

Hi Everyone,

I just updated my 2012 Passat SEL from the Factory RDS to a Kenwood DMX7709s to enable CarPlay and install a backup Camera. I know you used to be able to update the boot screen on Kenwoods with the Double Double Single Single on the corners but this does not appear to work on this unit. Can anyone help me with this update?

Thanks
