Radio plugs into Metra GMOS-04 adapter which connects to factory harness. This basically turns the head unit into a preamp as it uses the Monsoon amp to power the speakers.

Did you have to splice the sub wire into one of the speakers? That's what the directions say to do. Wouldn't that cause you to lose sound to that speaker?

I used the crux and my Alpine turns off with on star, but turns back on after ending the call. Still havent figured out, crutchfield offers tech support for free on installed equipment purchased through them. I just havent had a chance to call.

I did my H3 with a GMOS-01 (non-monsoon) and my H2 with a GMOS-04 (with Bose). No issues with either adapter. I used the same Pioneer X920BT radio in both trucks (flashed to X940BT software).

The H3 was a breeze to install, the H2 was torture - so much so that I basically never want to pull the dash apart again. Involved a LOT of trimming behind the dash as well to fit the headunit in.

Crutchfield sends a detailed master installation guide with pics but I also have hubby to help, my personal mechanic.

And sense I'll have the faceplate off I'm going to see about painting it yellow to match my exterior color like MustangGirl666 did in her build.

I'm doing that now I'm painting mine black, I already did the gauge cluster I'm working on the center and the shifter thingy. You know all the chrome stuff. It's not hard at all I can help you out with it.

What type of paint are you using? I just got the black paint to do all my outside chrome pieces. Post some pics when you're done & let me know how it went.

Im having the same problem stated earlier. My radio is on mute when I start up the truck. The only way to get it to un mute is to hit on star then hang up the call. The radio will then turn off and back on and the volume will be normal. I am using the PAC harness. Not sure whats going on. I have the monsoon . this is an unamplified system correct?
