i recently installed a avic D3 in my f350 without the gps antenna (it was in the mail) and did the bypass as stated in the sticky. it worked great, untill i installed my gps antenna, now when moving about 5mph, the sound still works but the screen says no video while driving or whatever. does this mean the bypass did not work? aslo, does anyone know where the vss on a 2006 f350 is?

thanks alot...

really? no one knows?

i will get the vss location when i go to work in an hour.. you will have it tonight

thanks alot sp4rt4n, but does anyone know if my bypass didnt work?? it worked fine before i installed my GPS antenna....

does it give you a parking brake must be applied message?

no, the video will work when sitting still, but when i move approximatly 5mph the screen goes dark and a message says something like "watching video while driving is illegal" or something like that....then when i stop it goes away, the sound from the video works the whole time...

yup your bypass didnt work

as for the vss

grey/black radio harness or abs module, pin 21

the ABS module is in the driver rear corner of the engine compartment
