Does this particular DD nav unit require that you tap into the VSS wire?

Thanks,

If I am mistaken, no you do not. You just need to run the GPS antenna.

 

Awesome Thanks

 

As the other person said, there is no vss wire on the 5120, just the antenna.

 

how is this unit? do you guys like it?

 

I have installed quite a few in the rather short time they have been on the market and I love them. There are nicer units out there, especially the Kenwood 8120, but for the price of about $550.00 you can't go wrong. The only thing that I don't like about it is that it only has two sets of RCA preouts, so if you are amplifying fronts, rears and a sub you have to split the front preouts for all 4 speakers to have a dedicated sub control. This means that any fading that you do must be done on the amplifier. This is the one advantage that the Pioneer AVIC-D3 has over the 5120, but I think the Garmin based nav on the Kenwood more than makes up for it.
