I just all of these pieces on order so i just want to clear up install.

With the parrot harness is the whole system plug and play to my OEM system? (2002 Honda)

I was mainly just wondering if I would have to hardwire the navigation, it is going to be in-dash btw.

It depends on the harness/vehicle. I used a QuickConnect Parrot harness for my vehicle with an OEM external amp. The harness includes a little box which converts the speaker level output of the ND-G500 to line level when sending it to the amp. It also functions as a mute box. The harness has a connection for a Parrot mute wire and there isn't an equivalent wire from the Pioneer. The blue/white amp control wire from the f500 is close, but I ended connecting this to a low voltage trigger (Peripheral TR-7) and a separate relay to fully ground the harness' mute wire. Works great, but took a while to figure out (credit goes to the installer). If you don't have an external amp, then the Parrot harness should be plug and play since the ND-G500 does the muting.

i'm using the nd6500 amp made for the pioneer f500bt. is that an issue?

No, not at all. That is what I use. I meant that your car may have upgraded sound with a Bose or Infinity (or the like) system. You will still use the ND-G500 to amplify the sound (phone call, nav voice, iPod) coming from the f500 and will be sending this out to the car's speakers. On vehicles with Bose/Infinity/etc amplifiers, the headunits typically output a line level signal (like a headphone jack) to the amp which amplifies it and sends it to the speakers (also allows for surround sound/subwoofers in OEM systems). The ND-G500 will be sending the f500 sound out at speaker level, not line level (i.e. at a level powerful enough to give reasonable volume on the speakers). If you don't down-convert (i.e. using a line output converter, which is part of that box in the Parrot harness I was talking about), then you will be doubly amplifying the sound which would be bad.

This isn't an issue if you don't have an external amp already in the car. In that case, the ND-G500 harness has standard ISO connectors. Just connect these to the vehicle specific Parrot harness (which is just an ISO-to-vehicle specific adaptor) and you will be good to go. Even if you do have an external amp, the connection isn't too difficult and the Parrot harness still makes it much easier.

One note of caution, on my ND-G500 harness, the accessory (red) and constant (yellow) wires were reversed in the double ISO connector (the big one). I read on here someone else had the some problem. It's easy to switch the pins. It's particularly important if you plan to tap into those wires to power accessories. I tapped into what I thought was the accessory wire to power my backup cam and drained my battery before I realized the problem. I also had a strange resister in the accessory wire which I needed to remove in order to get enough power to the backup cam.

no facory amp, just a base headunit.

so pretty much i hook up the f500bt, hook it to the pioneer amp ndg500, then use the parrot harness to hook it up to my stock radio?

this will power the nav and amp when the key is on?

Nick,

That's correct. It should get power via your OEM harness. That will provide 12V (acc and bat) to the ND-G500. The ND-G500 will provide 5V to the F500. It should work. However, as I said my setup did have a factory amp, so it's a little different. I've never tried using the ND-G500 as a mute box, but that is what it is supposed to do (i.e. pass the headunit audio through to the speakers unless it gets the amp control signal from the F500). Make sure you set the F500 audio to "Preout" in the settings menu. I also bought an external mic and active GPS antenna which definitely makes for an improved system. Make sure to tap the parking break wire (light green from F500 cable) into the black ground wire in the ND-G500 harness (or other ground) and modify the pioneer.ini file if you want to do the bypass. It's very easy. The instructions on moving the mute wire for a hardware bypass don't apply to the F500 (there is no mute wire in the ND-G500 harness - well there is a mute wire in the ISO harness, but it is just a loop that doesn't connect to the ND-G500 in any way). There is also a yellow constant power lead coming from the F500 which I believe I tapped into the constant power on the ND-G500 harness. I'm not sure what this is for as it is listed as "North American model only" on the F500 connection chart and doesn't power the F500 (that is done from the 5V black wire coming from the ND-G500). Maybe it needs to detect 12V as part of the "safety" system to make sure you don't use it while driving. The other wires from the F500 cable (rear view camera AV input and reverse-gear signal input) only are connected if you have a backup camera. Good luck.
