yea i think it definitely helps if you know a little bit about the roads there but that was not my case and i had to depend on the navi

i was leaving from northern blvd, the mapquest way is to take cross island pkwy to GWB to turnpike. I just don't understand why the navi doesn't give me that route as one of the choices. Guess i'll just mapquest next time

i already tried that, none of them takes you to GWB. They all eventually lead to the city and 495.

I have a D3 and it always tells me to go through manhattan city whenever i drive from Queens NY back home to new jersey. I've looked at multiple routes and fast/slow options and they all directed me to the city eventually. Mapquest directs me to take Cross Island Pkwy to George Washington bridge then to NJ turnpike which is WAY easier and faster. I'm sorry if i offend anyone for saying this but manhattan city has the worst roads and traffics i can imagine. So my question is how do you guys deal with this? do you mapquest instead? The D3 seems like to avoid easy roads and freeways as much as po

are you using a harness with RCA cables? if so i would get something like this instead....which is what i did. [/img]

after i switched to all wire harness with no rca cables, the whine disappeared and also the HU doesn't make a buzzing sound when the car is turned on. you might want to try that. i did the bose amp bypass and greatly improved the static noise that i heard from the beeps and voice guidance.

i went ahead and got a all wire harness w/o any RCA cables. It stopped 95% of the whine and no buzzing. Still a little whistle when all the lights and a/c are on, but i can live with it. But now whenever the voice guidance or beeps come on or press any of the menu buttons, i can hear a static in the background and it's not a clear sound. I think maybe the bose amp needs to be bypassed?

my d3 was locked also at one time until i reset it (at the front) with a pen. not sure why it did that.

i didn't understand the part he said about grounding the rca sheilds either. He must be talking about the rca cables off the unit and harness because there's none connecting to the amp. Care to explain? this is what my harness looks like btw:

so to ground the D2 chassis, you use a wire and hook it up to the back screw of the unit and the other end to the car chassis? also which chassis bolt off the car did you use? i have the same car

after some research, the factory amp has no rca plugs, they are just wires

if the rca cables are bad, i need to replace the whole harness?

the buzzing noise disappeared when i unplugged the front output RCA cables. I also saw no other bolt i could use for grounding besides the one i'm using now.

how exactly do you ground the shield of the rca cables? tape them to the headunit?

you don't hear the whine anymore after using ground loop isolators? any loss of sound quality?
