DIY Aux-In for Base Prii for under $100

eyesmell

Here's my solution to Aux-input in my 07 Base Prius. I'm by no means an expert at this stuff, and some people might correct me on some steps or explain how I could have done things better/cheaper/smarter etc...

I welcome any criticism, I just thought this may help some people looking to add aux-in to their Prius

Tools:

Cook Time: About an Hour

Directions:

First step is get your GROM Car2Aux installed and working properly. This video shows how it's done:
It took me two tries and about 20mins to get this installed.

(If you're attempting this, don't assemble the dash just yet, you'll still need to get behind there...)

After I got this unit installed, tested that it's working properly, I took the head phone cable and cut it in half with some wire cutters. The reason I choose this wire is because it had removable sleeves that you can screw on and off. After cutting the cable, I removed the sleeve and gold spring from the female end and set them aside for later.

I choose to put my aux jack in the compartment below the radio because I figured it would be easy to stash cables and iPod in there, and in case I made some sort of tragic mistake, it wouldn't be very noticable

I drilled a hole just large enough to shove the back end of the female jack through it. (If you're going to attempt this, please please double check behind the box to make sure there arn't any loose cables that may get cut by the drill. In my case there was plenty empty space behind the box so I didn't have to worry too much about the drill bit catching anything BUT YOUR CAR MAY BE DIFFERENT) It took me a bunch of tries because I didn't want to make the hole so big that the whole thing falls though. I finnaly got it just big enough so that the jack fit snugly in it and so that it won't come out if I pull too hard on a cable or something. I then ran the sleeve back up the loose end of the cable and screwed it back in as tight as I could to keep everything secure. (You can probably substitute the sleeve with a finely threaded nut if you can find one that fits)



I now had to put back the cable that I had cut in half earlier. I stripped both ends and there was only three different colored wires inside, so I matched up the colors and tied them together like so:



Tested to make sure it still works (and it did) and then soldered and taped the whole mess back together.

After all this I was left with two male ends, one from the cable I just patched, and one from the Car2Aux unit, so this is where the coupler comes in. (Initially, if you can find a similar headphone cable with two female ends, you won't need a coupler, but I couldn't so I did) I then coupled? both cables together and tested again, and everything was still peachy.



So I shoved the whole cable mess/car2aux unit behind the lower glove box, above the cabin filter....

...and reassembled the right half of the dash, and I am completly happy with my handy-work... for now

I must say, nice and clean job. Isn't there a cable available that works without all the wire work? Or, perhaps you were being particular with the mounting features.

I just got my GROM in the mail yesterday. I plan to instal this week. Your notes and video were helpfull. I'm thinking I might run the connection to the center console box.

I just bought all that I needed. However, I can't remove the cap from the

$12.99 6-Ft. Stereo Headphone Cable, 1/8" Jack to 1/8" Plug

to prepare for mounting. Is there a way to do this? It seems like they are loctited together or something. I feel like I would break it twisting it apart.
Yes, I purchaced the same one. Thanks.

Do you think the GROM unit works for the '09? The audio system is basically unchanged from the '08, right?

I really have no idea, last I saw, they had a compatibility list on their website.

Where did you see that?

The Grom Audio page says 03-08
GROM Audio compatibility: OEM integration

The In Dash PC page says 03-08

Where can I find the install video? YouTube has removed it for "copyright infringement"

And how can Warner Music Group "copyright" someone else's video showing how to install this?

It's probably the other way around. The video must have contained a WMG song in it and that's what WMG is objecting to.

Documentary film makers have learned a bitter lesson about this. Nearly everywhere you go, music is playing in the background. If you include that background music in your documentary, when it comes time to vet the rights you'll have to get rights to all that music. Consequently, many documentarians are choosing not to include this type of music at all, given the insanely difficult pathways to getting rights. When I shoot, I kill the incidental music or go somewhere else to shoot if I can't control it.

Copyright laws must be changed.

Does anyone here have any advice on how to install a JVC KD-HDR30 into a 2007 Base Prius?
