H3 in-dash computer installed

[JeffW]

I thought folks here might be interested in a little project I've been working on for a while to replace my head unit with a computer to handle music, nav, camera duties and more.

Some of the advantages of building this system over an OEM or after market system include:

Graphic design ? It seems every other nav system is blue. Blue graphics look great, but unfortunately the H3 doesn?t have any anywhere else in the cabin, and thus looks out of place. So I designed an interface that made use of the yellow, red, and white colors that are used elsewhere. I also utilized fonts and other design elements from the HUMMER logo. In fact, I wanted something that looked more OEM than the OEM.
Topographical mapping and tracking. I used TOPO! for this.
Wireless synchronization of music database. In my driveway I just press a button to download any new songs from my home computer. It?s also used to update other software, including navigation maps.
Sirius radio that shows what?s currently playing on all stations, and song info that isn?t limited to 16 characters (or some other small limit).
Gesture interface. A quick an easy way to skip a track or change stations without taking my eyes off the road.
No nag screen for the nav.
Volume knob. Most nav system use push buttons for volume... I hate that.
0-lux backup camera. I used a backup camera with IR LED's to produce a clear image in complete darkness.
Extra spotting camera. Installed underneath the chassis aimed at the front wheels, to reduce need for a spotter when off-roading. (coming soon)Hardware:
Intel Core Duo processor
iBase MB899 mini-ITX motherboard
DSATX automotive power supply for motherboard
DS12V automotive power supply for amp
Xenarc 7? LCD touchscreen 700TSV
Mechatroniks chassis
Alpine Sirius Radio tuner SIR-ALP1 with MithJS interface board
Peripheral GMAH24B for retaining OnStar
Phidget encoder (for volume knob control)
Volume knob from stock head unit
Backup camera
GlobalSat USB GPS antenna
Seagate 100GB 2.5? hard drive

Software:
Windows XP Pro
Road Runner - Thanks Guino!
CFX skin as a base - Thanks b8bboi and Proximo!
iGuidance
TOPO!

These two pictures show the completed install. Note the volume knob lifted from the original head unit, where it was used for tone control. The rubberized texture and color of the knob matches the other knobs in the cabin, such as the A/C and vent position knobs. I was also able to perfectly match the color and texture of the screen bezel with the plastic surrounding the A/C vents at the top of the picture.

Here are some screen caps of the various functions:
The startup screen. In the upper right corner is the clock and below that, ?ONLINE? illuminates when I?m in range of my home wireless network. The icon on the bottom right is a button for synchronizing with my home computer.

Selecting the WEATHER button above takes you to the current weather screen. It is updated automatically if online.

It also features a 5-day forecast screen.

On the main menu bar on the left, MEDIA is for the library of mp3?s.

RADIO is for Sirius satellite radio. Currently there is no AM/FM radio, but I can add it if I ever feel I miss it (I don?t think I will). The FAV button on the bottom cycles through lists of favorite stations. The name of the list is at the top, ?Jeff?. SAT: and TER: show the strength of the satellite and terrestrial signals respectively.

Road Runner embeds the iGuidance program natively. I?ve used quite a few nav systems, and am pretty happy with iGuidance. It uses NavTeq maps, which I have found to be more accurate in my area, as opposed to TeleAtlas. When navigating a route, I can be in MEDIA or RADIO, and for each turn, it will automatically switch back to NAV, lower the music, speak the direction, and then return to MEDIA or RADIO when I?ve completed the turn.

TOPO! integration works quite well, also. I had to make some custom AutoIt scripts to pull it off. The ?+? and ?-? at the bottom are for zooming in and out. ?TRK? will start plotting your position with a red line (example shown). ?FIND? will pull up the screen that searches for landmarks. ?OSK? is an On-Screen Keyboard for typing in what you want to search for.

The backup camera is enabled whenever the truck is put in reverse. The Xenarc display has an AV2 composite input that it will switch to automatically whenever there is a signal on it. So I simply power the camera off the backup light leads. That way the camera powers up and provides a signal whenever I?m in reverse.

make me one

[Mr_Pat]

Wow incredible!!!! How much did it cost to put together?

[ChiHummer3]

Very cool! Great job!
:beerchug:

I'm guessing it cost him at least $99...

[Steve - SanJose]

Amazing, but I don't know the cost....

[JeffW]

Not if you get it at Pep Boys ;)

I lost track of the cost, but if I did it right from the beginning I'd say a little over $2k. Alas, I bought a lot of wrong or uneeded stuff. I also underestimated the cost of the little things you don't think of, like wire, fasteners, tools, etc. I even had to buy a whole new soldering station because my old one wasn't cutting it with the SMT chips in the amps.

[Mark805]

Thats just amazing....

:perfect10s:

Very impressive.. now make it into a self install kit and make yourself some serious $$$ on Ebay

Mark, good to see you're still slumming it over here in the H3 section ;) I was keeping an eye out for your new rig at the Cabin Creek Hummer Happening, but didn't spot it. Were you there?

Actually the StreetDeck folks are already pretty far along on that idea... http://store.mp3car.com/Mp3Car_Infill_G4_powered_by_StreetDeck_p/sdk-014.htm I experimented with this software but it wasn't quite right for what I wanted to do, but I think it will be someday soon.

That is off the charts, no bullsh!t, the coolest thing I've seen in an H3. Not to be confused with "on" an H3 ... Humbebe's custom H2O rig still holds the title there :D

Question - what about temperature issues? Your setup looks very efficient, but I have to be careful with cooling in my full-size ATX box. Can you monitor case temps from the LCD?

[Agriv8r]

:beerchug:

[marin8703]

Thats a sweet setup. Great job!:clapping: Submit your design to GM, Hummer, maybe it'll become optional sometime.:excited:

[lotus4s]

AWESOME! :perfect10s: :perfect10s: :perfect10s:

Thanks. Yes, I monitored the temps from the LCD for a while, but now I don't, to reduce clutter. I went on a long trip on a 100 deg. day and it seemed fine. I noticed it does get quite warm behind the dash. I think the LCD is the biggest heat generator. However, I have it set to alarm 50 deg. C and shut down at 60 deg. C, which is pretty conservative and it doesn't really get close to that. When I had it on the bench the CPU fan never even turns on it, the case fan kept it cool enough. In the tight quarters, though, the cpu fun does run quite a bit, but seems to do a fine job. The Core Duo proc is pretty low power.

cool stuff, now how much for hardware and how much for labor ?

Man That rocks... !!

Now all you gotta do is take orders from us lazzy 3'er's who want one..

[H3slate]

That is really cool! Are you able to easily update/add mp3's to the hard drive? Sorry, just reread original post and got my answer.

[Mark805]

Mark, good to see you're still slumming it over here in the H3 section ;) I was keeping an eye out for your new rig at the Cabin Creek Hummer Happening, but didn't spot it. Were you there?

Yes, I was there in the morning session. I went on the "experienced" ride. It was actually pretty fun until i let my girlfriend drive part of it (Got my first scratches :rant: ) But if i hear "Torque is your friend" one more time I am gonna go postal.

But once again I had a great time. After the event I went exploring on some of the logging roads out there and actually found a pretty good spot to access the Yakima River to toss my fly line.

Back to your system... I am really impressed with this setup you got. Now have it look for unsecure wifi and cruise the net too!

[Sewie]

WOW.......just, wow!! :perfect10s:

That is just incredibly cool!

[RuggedH2]

WOW.......just, wow!! :perfect10s:

That is just incredibly cool!

X2 that is amazing!

[WikidPete]

Nice Job!!! Very cool setup!! :perfect10s:

[HummerHawk]

Does it take long to boot up each time, or is it in like a standby state?

And very cool, that's awesome!

[XM DUDE]

I wish GM would do this in their vehicles.

[JeffW]

Right, I have it set to go into standby when the accessory power is off. So when starting up, it only takes a couple seconds for music to start playing. I installed an Optima Yellow Top deep cycle battery in case the current draw was too much for the stock battery though.

[usetosellhummer]

good gawd man! your new name is Scotty! can you beam that into my rig.
wow wow wow

[evldave]

Very nice setup! Very professional looking and quite functional! I also use TOPO! a lot, if you want state data files let me know via PM (I have WA, OR, ID, CA, AK, MT, IL).
