Ultimate Scion Headunit (stereo) thread
 

I've been looking for a central resource for the Scion head units with no success.

After hours of searching on 4Runner and other Toyota forums, I've created a master list of all the head units (at least the ones I could find information on) and their capabilities. I'n sure I'm still missing information about each head unit, so feel free to post any udpates you know about and I'll be happy add them to the list.

I'd like to eventually get pics of each of the units as well (front and back), so if you have a particular unit, send me the image link and I'll post it as well.

Wow. Wish you would had posted this a week ago before I bought a T1807 thinking it had ipod connectivity and color changing LCD.

Good work. A clean and easy to understand summary.

Thanks. I've been researching this for a couple of weeks because I'm trying to find the best upgrade for my 4Runner.

I think i'm gonna try and find a Premium HU (T1809). It looks like it has everything except the 6 disk changer.

So if all you want is the radio to work, (not the sat and ipod) are all these plug and play for the 4th Generation?

I have an 1807 that was a "drop in".

From what I've been able to find, they are all plug and play (of course I'm not an expert, just a data aggregator :)).

Edited thread title
 

Corrected a typo to make it easier for future searches.

I am picking up my 1809 tomorrow and will install it this week. I will be sure to post pics when finished so everyone can see how it looks in a 4th gen. Im looking forward to getting it in there.

EDIT: here is a pic...

This is sticky worthy (for a while anyways...:D )

:cheers:

SWEET....my first sticky! :trophy:

The links to the info on the iPod cables were truncated when posted. Is there a way you can repost the full link?

Let me see if I can find them again.

ki soarer - looks great!
Are you still able to use your steering wheel audio controls?

Will any of these work for a 2003?

Update: Sourced a T1808 on CL for $60 and the guy was local.

I've got a 2003 Sport without JBL.

Plug and Play! Sound quality is heaps better. Steering wheel controls jump through presets now instead of browsing through stations.
I don't have an aux jack so I can't comment there. iPod cable is on the way. Also looking at an integrated bluetooth module too.

If I had one complaint it would be that the orange doesn't match the rest of the interior lighting.

Also, when reassembling, leave the 2 bolts on the side of the head unit a little loose. When you put the front bezel on you can center the radio in the opening and then tighten the bolts.

Subscribed. Very interested in this since I too want to upgrade my head unit. How much does the Scion unit go for? Are you buying new from Toyota or used from e-bay or such? Thanks.

Hey guys, I have an 05 sr5 4runner with the stock headunit. I am a bit confused about some of the terms used here. I would love to connect my ipod to my stereo through the ipod dock connector, and it seems like a used scion HU might be the way to go. What exactly is the harness, though?

I don't necessarily even want to control my ipod with the head unit, I am just considering an upgrade from the tape adapter (and hopefully a cleaner look than having cables all over the place).

Thanks for the help.
