i wrote a custom app to make the steering wheel buttons work.

nothing else is custom. however, i am running a non-standard ROM (CyanogenMod 10) and therefore have root access too, but that's all pretty standard stuff among the Android mod community.

the majority of the customizations (like having it go to sleep and wakeup and turn on/off the right things when it does) are done with a wonderfully complex app called Tasker.

speedometer discrepancy:
40 is really 45
50 is really 56
60 is really 68
70 is really 79
75 is really 85

never had really thought about the math on the speedo before to realize that the amount you are off by gets worse as you go faster!

all calcs came from: http://www.4lo.com/4LoCalc.htm

UPDATE after lift install 6-29-08:
the computer says i am now averaging 12.5mpg, which i calculate would really be 14.1mpg if the computer was adjusted for the new tires. before tires and lift, i averaged 16mpg, so it looks like just the change in weight and aerodynamics has lost me 2mpg!!
where can i get the gears you have listed?

Which apps do you feel are necessary on a Jeep mounted tablet? Which are you running?

Mapping apps...
- Google Maps (street, online)
- CoPilot Live (street, offline)
- Backcountry Navigator (topo/satellite, offline)
- OruxMaps (topo/satellite, offline), better in some ways than BCN but has limitation on size of downloaded area currently

An OBDII app...
- I use TouchScan, Torque is more popular

Viewer apps...
- a general document viewer for excel/word/etc like OfficeSuite Viewer (i have a list of OBDII codes in excel format)
- Adobe Reader for a copy of the factory service manual

Lux (lets you set the screen backlight much dimmer than normal for night time use, not necessary if you have certain custom ROMS though)

An automation app...
- these sort of apps let you do basic stuff like tell the tablet to go into airplane mode to save power when external power is disconnected, or advanced stuff like start an FTP server when your near your house based on which cell tower it sees.
- Tasker rocks, but it's got a steep learning curve
- AutomateIt has a much cleaner UI, but i've not used it personally
- llama is a popular free one, but a bit limited

A media player app...
- I'm using "PlayerPro Music Player" with the Holo ICS skin, works for music and video

Streaming media apps (if you have a 3G/4G connection or can tether to your phone)...
- Pandora/LastFM/Spotify/Etc.
- Youtube/Hulu Plus/Netflix

Weather apps (if you have a 3G/4G connection or can tether to your phone)...
- i'm using HD Widgets
- i also have Weatherbug Elite for more detail

Some basics...
- a file manager, i like ES File Explorer better than ASTRO
- a backup app like Titanium Backup (not only making it easy to backup the entire config of the tablet, but also can get rid of annoying built-in apps from the phone company)
- maybe a task manager, but i rarely need it - depends on the device and the version of Android

i consider root access to be a minimum personally so i can do whatever the frig i want with it, but you don't NEED it. i actually like to run a custom ROM too, but that's definitely not needed.

in addition to all the above apps, i have my custom app for interfacing with the steering wheel buttons. i've also done a lot of customization with Tasker. finally, since i have root and am messing with behind-the-scenes stuff, i have SuperSU and Better Terminal Pro.

i'm using a USB one: http://www.amazon.com/ScanTool-42300...dp/B002PYBZJO/

my custom dock to connects to a USB hub so that i can have multiple accessories connected via USB. currently i'm only using bluetooth for the audio because i couldn't find a USB sound card that Android recognizes.

That makes sense in your case. Any recommendations on a Bluetooth adapter for the obdII

the OBDLink MX and the PLX Devices Kiwi are the top end, but they are expensive. i'd probably try one of the cheap ones off amazon that has decent reviews first. sorry, no personal experience with any of them. let me know what you get and if there are any problems with it plz! i want to get one eventually and make my steering wheel interface app work with it so that it can benefit more people.

Thanks for the input! I look forward to trying this out with my tablet. Now I just need to figure out a mount. I don't care for anything on the market. Any advantage of TouchScan over Torque??

i just liked the UI of TouchScan better for just a basic OBDII app. Torque has widgets and lots of extra little features if you're into that, the ricers love it!

good warning, i had bought a $10 sb one from ebay and it only worked with certain protocols of obdII. the $25 one i got from amazon works great though, but it's a recognized brand (scantool.net). it's too bad there seem to be no reputable inexpensive bluetooth ones.
