Not as easy as described...

First, i bought the adapter, (VWA-3B) doesnt fit into the nav radio, looks like it is for an aftermarket unit, which one do i need...

Second, walmart doesnt sell the removal tools, i used a couple pampered chef pearing knives to get it out, wish i had the right tools for this....

Third, i think i have the 2 extra wires already in the harness... there is a total of 9 wires in there, does that sound right?

other questions...

Where does the changer plug in (or ipod adapter)

On the standard unit there is 2 connector looking objects next to the main harness, on the nav unit it is covered up....

What is the plug above the main harness (it is on both units)

I think that is it for now...
Thanks in advance!
