I did the install using the Axxess XSVI-5524-NAV harness in my 2014 Ford Transit Connect. When I first turned the system on, everything worked OK, but when I switched to the Map mode, the unit reported that it didn't find the Vss signal, so it would revert to the hybrid mode. This was evidently caused because I had the switch in the Accessory position and not the On position and the 'brainbox' with the harness doesn't output the Vss signal in the Accessory position
My question is . . . . will the unit recognize and make use of the Vss signal when it's present or, will I have to pull the
