Those of you who've installed it, where in the car did you put the unit and the antenna? Trying to see if I have to run the lines all the way to the trunk or maybe there is a better option.

Ask member LS2 MN6. Not sure why but, for some reason, I recall him having that unit in his car. The mind can be a strange thing sometimes.......

I mounted the antenna on the roof centered just above the back glass, used a credit card and pushed the wire under the weather strip and ran all the way up and came in the drivers door jam and in through the loom that goes to the door, the module will fit under the center console just behind the shifter, on a m6 idk about a auto car...The pioneer Bluetooth module is even larger, it was the pain to find a place for it

Thanks. It hopefully it makes it easier to install in front. Fortunately I don't have to deal with the BT module. You just tapped the yellow wire to the yellow on the harness?

I do have that unit!

I mounted mine on the trunk decklid just behind the CHMSL. I ran the cable from the XM Module (which is mounted in the trunk), up the gooseneck (ziptying it to the existing bundle, and then wrapping it back around under the felt on the trunk lid. The weather stripping of the trunk does let a tiny bit of water in if you directly spray that location, otherwise no leaks to speak of.

I can take a picture of my mounting location if you so need it.

Could you please? Much appreciated. Also the yellow wire, did you tap that into the yellow wire of the harness bundle at the tail light?

Most awesome. Thanks.

Okay. Got it, thanks.

Thanks for the pic MN6. Probably better there than the gas tank cage I was thinking about.

Did you all put anything between the antenna and the lid? Trying to prevent scratches.
 
#14 ·
I didn't put anything between the lid, I do have some scratches but nothing I'm overly worried about (my front end is a rock chip nightmare since mine is a DD). If you don't want scratches, then take the antenna off (throw it on the underside) before using an auto car wash. Other than that it really never moves (and thus never creates scratches).

You'll have to cut some "relief" into the felt that sticks on the gas tank if you mount the XM Module where I did (I basically cut two 1 inch cuts in it, never removing any material, just cuts). I tried to take a picture of that with my iPhone, but it came out fuzzy.

I Understand what you're saying. Did you ground it on the frame? I can't quiet tell.

Never had a check antenna issue.

If I start the car in a place with weak signal I don't get the fancy station icons on my preset list, but that's it (I have the Z130BT Software on my HU).

How is your antenna routed? The reason I put mine in the trunk is that is where most OE's put it as to make the antenna routing as short as possible.

Ran the cables for XM and the back up camera to the front. Now going to tap the XM and the back up camera into the tail harness. Just confirming my wires. Reverse camera positive into the light green and grounds for both into the black. Correct?

Brilliant. I had that messed up. What I had labelled as constant power was actually Pin 4/Backup Lamp PS on the female plug. Still looks like yellow under light. Also I didn't see the blue stripe on Pin 1 Ground.

Thanks again for the information and your patience.

Yup. Same here. Especially since the last time I swapped a radio it was on a '95 Villager and literally plug'n'play.

Now on to soldering the speaker wires of the radio harness and the brake bypass.
