I have been a member for a while now. I just picked up a nex-5100 from a friend who traded in his truck. I have hooked it up in my 2007 Sequoia and it works great. The issue I am having is the speed reading for the nav. I have done the grounded parking brake bypass with the quadrant shut off,and have the vss wire hooked up to the proper signal. The speed reading on the unit is half the speed of the truck until 33 mph,it does not read higher than 33 mph no matter how fast I am driving. Is it possible that having the parking brake wire grounded may be throwing it off. Any help is greatly appreciated. Thanks, Steve.

factory reset

Ive done the factory reset about 10 times ,unplugged the unit,reset button,navigation reset.

Disconnect the VSS wire, the unit will then just use GPS to get your speed, works great on my 06 Escape

Same here. Never needed the VSS thing at all. The speedo vs. GPS unit speed diff is only about 1-3 MPH at any given time.

I wish I could just get rid of the GPS speed thing entirely though...useless IMHO.

i tried that as well and the nav wouldnt respond at all

Just as a note, I unhooked the park brake ground and reset. Now all is well, thanks for the replies and help.
