By "deck amp" aka preamp, they are referring to the radio's built-in amplified outputs (which generally will be like 30Wx4 max, which is crap). But like I said, a lot of these navigation units don't even have amplified outputs - don't know about the N2 specifically. The stock amp refers to the car's built-in audio amplifier (part of the Bose system, for example) that handles amplifying and distributing the sound to the stock speakers.
If you're still getting a buzz, especially when accelerating, you definitely have a ground loop problem and really should get the ground loop isolator. Circuit City, Best Buy, etc. installers don't know **************** about how to install something the right way, and just rush through the installs anyway.
