FINALLY figured out the noise problem... I used Scosche’s FDK11B Audiophile harness: http://www.scosche.com/products/productID/581 This harnesses comes with a separate connector for the subwoofer (the smaller one in this picture) . This connector has 6 wires coming from it but the Edge doesn't use all of them. I Used the wires that match up with the factory’s harness. But in the factory part of this harness, there is a bare-looking ground wire that matches up to nothing in the Scosche harness. Today, I just connected the bare-looking ground wire from the Factory subwo

Well - a year later and I'm still having this buzzing sound from the subwoofer when the headlights are turned on. I removed the voltage regulator from the sub's amp remote wire and replaced it with a 5.6k resistor. Still have the buzz/hum sound from the sub when the headlights are on. Any ideas ?

The usefulness of the NAV varies depending on the situation. There seems to be some bad logic for calculating the shortest route in certain cases. For normal day to day use, it works OK for us. But I'd never solely rely on it to plan a drive of over an hour. Have a look at these two threads: http://www.avic411.com/forum/viewtopic. ... highlight= http://www.avic411.com/forum/viewtopic. ... highlight=

I don't have my VSS wire connected right now. The D3 has my speed PERFECTLY matched to my speedometer. I don't think it's using the gyros to calculate speed. It can calculate your speed from the GPS signals - like any hand-held GPS can do.

If they're treating their customers like crap and ignoring problems reported, then who cares if we irritate Frank !! I will call him for sure. Be polite and professional.

I really don't think it's learning at all. It's just that the calculation is different in one direction verses the other. It's also probably that you were driving faster than the average speed in the D3 for the road you were on. EVERY time I calculate the route from Northern Virginia to Duck, North Carolina, it comes up with the same, ridiculous, overly-long route. It's learned nothing from the couple of times I've driven that route.

If so, please use your NAV to calculate the shortest route between Northern Virginia and Duck, North Carolina. As you can see from my post on the D3, it does a terrible job with this particular route. I'd like to see the results from a different Pioneer Unit. http://avic411.com/forum/viewtopic.php?t=8403

Is the D3 the only bad trip planner / route calculator of Pioneer's fleet or are they all quirky ?

Can someone post the number to call for the correct person at Pioneer ? Also - has anyone tried comparing the D3 with other model Pioneer's to see if they're any different ?

See the thread I started a while back about the D3 being a bad trip planner. On my vacation from Northern Virginia to Duck, NC - the D3 was suggesting that I go WAY, WAY out of my way and never could come up with the correct route: http://www.avic411.com/forum/viewtopic. ... highlight=

At your advice, I hooked it up to the purple/white parking lights wire in the driver's kick. are you hooking the purple/white from the d3 to the parking lights? only reason i ask is that is the reverse wire, not parking lites. pl wire is orange/white. No - I've got the correct wires from the D3. The screen dims properly when the lights are on and my reverse camera works properly when I'm in reverse. It's just that recently, I started having this buzz through the subwoofer when the lights are on.

Nope - nothing aftermarket - except for the D3 and reverse camera. Haven't had a chance yet to try removing the voltage regulator...

At your advice, I hooked it up to the purple/white parking lights wire in the driver's kick.

I installed the voltage regulator several months ago. I didn't notice this buzz until just recently. It's odd that the buzz is only there with the headlights on and only through the subwoofer. All other speakers are noise free. I guess the voltage regulator would be a good place to start. I can remove it easily and will see if that eliminates the buzz.

All my connections seem solid. But when the headlights are turned on and the D3 dimms, there is a slight buzz from the subwoofer. I've done the voltage regular to eliminate the turn-on thump. But just started hearing this buzzing sound lately. Any ideas ?

It's almost like the engineers at Pioneer are playing a joke with that horizontal line background. It makes the display look defective. I've seen that comment many times on this forum and when I originally saw that background, my first thought was that something wasn't right.

I would think that changing the speeds would change which route is calculated. If you are looking for the fastest route, and your highway speeds are set faster than the standard, it would probably be more likely to route you to a highway, then have you take back roads all the way. Aren't highway speeds set - by default - as being faster than secondary roads ? The D3 shouldn't avoid highways unless you specifically tell it to. By it's OWN calculation, when I ignored one of its turn commands and finally got it to follow MY route, it immediately knocked off 80 miles in an instant. At tha

As far as I know, increasing the average speeds will do nothing to help it pick better routes. It simply helps it make a better ETA calculations. The multiple routes options may help you find a better route. In my case it didn't but others have reported success with this option. I still don't understand why the D3 can't pick the best of the multiple routes it suggests, based on fastest time or shortest distance. dalbert Any report back from your test of making Duck, NC a destination from your location in Northern, VA ?

I live in Northern VA. Tomorrow Ill try entering a route to Duck, NC and see what kind of results I get. They maybe different, who knows. Please do ! I would be quite surprised if your D3 didn't calculate the same 400 mile route that mine did.

Well, I guess on certain routes it does OK and on others, it just isn't intelligent enough. The route it picked for me on my vacation was pure and simply bad logic somewhere. I've tried a few others lately and the route it picked was OK.

Regardless - on my trip from Northern VA to North Carolina, the D3 put me on a course that was over 400 miles and over 7 hours by it's own calculation. Every one of it's 6 routes took pretty much the same distance and time. HOWEVER, when I finally forced the D3 to use the route I thought was better, it - by it's own calculation - came up with about 300 miles and 5 hours. It did this without me changing anything in the average speeds for certain roads. So, I don't see what difference it would make to change the. average speeds of any road type. The D3 is calculating the distances and

I just tested the multiple (6) route option with my Northern Virginia -> North Carolina route. I looked at every one of these 6 routes and every one of them completely avoided the most obvious short route as shown in the picture I attached from Yahoo! maps. I tried shortest and fastest route. Same results. So for whatever reason, the D3 will not take the shortest route on this particular trip. It just refuses to go down route 64 - the very obvious straight line between my two travel points.

I have no problem with the time estimates given by the D3. They are fine by me as default. My only concern is that it can't consistently find the shortest route. That's an odd glitch - and I'll guess that it happens both on fastest or shortest route. If the D3 can find 6 routes, why can't it pick the shortest of the 6 as it's first choice ? I agree that on a long trip, I wouldn't rely on it or any other nav solely. But I was still pretty shocked that it put me on a route that was 100 miles longer than necessary on a trip that's only 300 miles.

I do see the thin red line that keeps pointing towards the destination (kind've a nice feature). But I've not seen the D3 display a straight-line distance - because on my trip from Northern Virginia to North Carolina, the straight-line distance would have been under 300 miles and the D3 immediately showed just over 400 miles - just after calculating the route.

Maybe it just screws up certain routes. BTW - I also plotted my Northern Virgina home to my Parents home in Pennsylvania. Yahoo, Google and the D3 were all within a few miles of each other and I actually liked the D3's route better ! But I don't understand these "as the crow flies" distance comments. When I routed the D3 from Northern Virginia to North Carolina, the FIRST distance it gave me was 400 miles. That's definitly NOT as the crow flies unless that Crow is drunk. The actual driving distance is only 300 miles if you don't take a ridiculous route.
