Installing Pioneer AVIC-X930BT in my 07 STi...help?

93V · 01-06-2012, 08:41 AM

Did a bunch of searching and I have some questions/concerns to sort out. Hopefully you guys can help.

1) I'm trying to figure out what to do with the blue wires on the two harnesses. On the harness I bought from Crutchfield, the blue wire is designated for "power antenna". On the harness that came with the head unit, there is a blue/white wire that has a description for it in the manual as follows: "To auto-antenna relay control terminal. If the vehicle has a glass antenna, connect to the antenna booster power control terminal (max. 300 mA 12 V DC)." This same blue/white wire also has a sticky tag on it that says "System Remote Control". Should I be connecting the two wires? For the installation procedure for amps, it shows the blue/white wire being used as a remote turn-on for the amp. I think that I'm supposed to connect the two blue wires together unless I get an amplifier. Thoughts?

2) Does the GPS antenna need to be visible? I read some posts about people putting it behind the clock and it works fine. I have an ATI clock pod with gauges, but I'm sure I can fit it under there. Just not sure if wires being near it will screw with the signal. Thoughts?

3) Do I need to connect the Vehicle Speed Sensor and Reverse Signal wires? If so, can someone point me to them?

I believe that's all I have for now. For what it's worth, I'm trying the install with the system bypassed using a technique I found online and on youtube.

Thanks in advance for your help.

From what I remember with my F900BT (thank goodness you don't have that piece of crap), the blue/white is your amp turn on and your pure blue coming from the headunit is the antenna wire.

If you only have a pure blue on the headunit going to the car and no other blue wire coming from the headunit, then connect the two together.

I recently gave the Walmart Pioneer package deal a try and had to end up returning it due to Pioneer being cheap and not putting a dimmer in the headunit so there was a blue light staring at me while I drove at night

There was no blue wire from the headunit and I couldn't get AM reception until I connected the blue/white to the blue wire.

I recommend having the GPS antenna visible for best reception, though it's not 100% necessary. On my Legacy, I put it to the far left of the dash (as viewed from the driver's side) and ran the wire down through the rear of the fusebox and under the steering column, taking care not to get it tangled in anything.

The VSS helps if you're in a tunnel. The reverse sensor is only used if you have a backup camera. Since I don't drive an Impreza, hopefully someone else can chime in as to where they are.

thanks for the reply...i installed the radio and everything works fine so far except the GPS. sometimes it doesn't work, sometimes it works just OK. it has trouble positioning my car well.

i followed suit from an install i saw on iwsti.com and attached the antenna on top of a metal frame piece behind the radio underneath the clock pod area. i could take the antenna out in the open and see how much of a difference it makes i guess and go from there.

curious if anyone else has a GPS antenna under their clock pod/behind their radio (hidden) without any issues.

I have a under clock pod with no issue. Had a 900bt before upgraded to x940bt, same location, no problems at all.

the GPS antenna can just not be blocked by a piece of metal directly above it. I typically put the antenna right on the top of my deck's when doing installations. Never had a problem.
