I just bought the F900BT and there is no pink wire on the harness and no VSS wire labeled. does this unit not need one or do i have the wrong harness? the nav picks up ok because of the gyro but i want to know if i need to hook the pink up. any info would help. Thanks.

It is very unlikely the harness you purchased (or the factory one) will include a wire labeled as "VSS". You will have to do some research to determine what wire will provide this for your specific vehicle.

You can ask on this forum for the specific information for your year/make/model vehicle, or search around on other web forums for your vehicle type.

The 900 harness has a pink VSS wire in the main power harness. If yours doesn't have one, you have the wrong one

nvmore100 What r u talking about!! I have been an installer for 20 years and every car navigation with the exception of newer ones that use the gyro has a tagged VSS wire in the harness. year make and model has nothing to do with my question, I know the 900 manual says its there but my harness does not have it so thats why i am asking. if you don't know anything about electronics and you clearly do not, Don't answer questions that are related...
