Dimmer = lighting switch

The "power antenna" in our cars (actually an antenna amplifier) needs more power than aftermarket radios send over the signal wire. You need to connect it to a more powerful +12v source than the "power antenna" or "remote" or "amp signal" wire. Good sources are the cigarette lighter or the big red switched power wire that powers the radio itself.

 

Ok thank you for your help!

 

So did my install today. Can not get the steering wheel controls to sync with the D3....i bought the metra
kit wired it using the above link. Will not pick up the D3 checked all connections twice. Any ideas?

 

Unless you've wired it wrong, you may have to resort to manually programming it - http://www.axxessinterface.com/pdf/INST-ASWC_Web3.pdf

 

I need help please. I installed metra kit and pioneer 8400 also aswc steering wheel and PAC OEM-1 harness. After testing it in car all worked fine except my amp did not turn on. I have my amp in truck tapped wired to another amp and subwoofer. Anyways as I was testing the head unit I turn on te car to save my batter because I was on ignition switch I hear tick sound and I see harness PAC OEM-1 smoke so I turn everything off. I open te harness looks ok. I test te wires. Red wire with voltmeter to see if power is coming from out put of harness all is still good. Put my new radio won't turn back on. I tried to put back my old unit and ac turns back on and factory radio doesn't work. But the metra ac control works when I connect it. Wierd. But both after market pioneer radio and factory won't turn on. I don't get it. Please need help

 

I also checked all fuses all good. And is te yellow battery line from harness was reading on voltmeter .63 volts. Is it should be 12v? Red ignition line was 12.62 volts. So that was working fine on the PAC OEM harness output and input I was making sure there was still power coming to it. I Ben tested the radio pioneer on different car works fine. So u think I need to replace my harness PAC or something shorted out in my car?

 

thank you, I'll triple check tomorrow.

Also another problem I have is my XM radio presets don't save. If I leave the car off for a few minutes then restart, all of the presets reset, any ideas on this?

 

Yellow wire going to the radio should be constant +12v, car on or off. Red should only be +12v if the car's on.

 

still having trouble getting my XM presets to save. If the car stays shut off for more than 5 minutes all presets reset to station 1 (the free/testing station) I've ruled out the constant/power wire because my FM stations and clock stay put. It's just the XM stations. Anyone have any ideas? Pioneer Avic D3

 

Bad xm receiver?

 

I still get stations no problem and can preset them while the car is on they just erase when I restart. I guess that could be the problem.

Clarifications on 03-04 metra trim w/navigation.
I modified some of the text to try and break the in-line text ads, since it was pointing people are the wrong stuff. Worst probably being where it said "Metra 40-NI10 - AM/FM antenna adapter." and antenna adapter was getting hyperlinked to some antenna adapter for who-knows-what on crutchfield.com. I understand that these sponsored links help pay the bills here, but when these things destroy the integrity of a message you gotta do what you have to do in order to keep the message clear.

Thanks again Wrathernaut!

 

Glad it worked out well, only thing I would have changed would be the use of the front-facing USB. I'd never cut a factory panel like that for wires. It's too late now, but if you take the radio to anyone with some decent soldering skills, they could attach a USB extension cable internally and have rear USB or 3.5 easily - Or I'd just buy a radio with rear inputs to avoid the situation entirely.

 

Yeah I will admit that I wasn't really happy that I had to cut into the OEM plastic.

Nevermind. I misread your post.
