Sorry if this has been covered before. I searched but didn't see exactly what I needed.
I just bought an 06 Ford Expedition Limited that has a Z1 installed already. It does have a 2way toggle switch under the steering wheel that I have discovered turns the display on the Z1 from daytime-nighttime.
The Z1 date is MAY 06. The vehicle has auto lights so not sure to go about bypassing the lockouts.
Any help or a link to a thread would be great!
