Does the 110BT have the threaded hole on the back so that you can run a reinforcing strap to the dash? These units are pretty heavy so I want to run a strap from the back of the unit to help relieve some of the stress on the bracket but I can't remeber what size screw I need. I think I remember it being an M4 on my old Z2 but if someone knows for sure I'd appreciate it if you could pass that along.

Thanks,

ths install manual will tell you

I had thought that the install manual would have it too but it only describes the screws for the side as 5mm X 8mm.

just unboxed mine - and it does have the threaded hole (8mm max depth for the screw).

So I'm assuming that it's 5mm X 8mm just like the ones on the side.

Thanks,

Mike
