Really nice looking project. I'm looking to scrap my current CarPuter and install a tablet. I was debating back and fourth between the Nexus7 and the Tab2, but I think you sold me on the Tab2. I do have a few questions though:
1) Overall, how's the sound quality going from the headphone jack? I'm not a huge audiophile, but I definitely like things to sound clean. One of my biggest issues with my CarPC now is that I could never get the music to sound quite right while using iTunes, Centrafuse, or damn near anything. As a follow-up question to that, what did you use for equalizing software/apps?
2) You said that you had most of your data stored on a 64GB SD Card, but Samsung's website states that 32GB is the max...can you definitely confirm that you are using a 64GB stick?
3) In your videos, are you still using your iPhone, or did you switch to something else? I currently have an iPhone 5 and I'm wondering if I'd be able to jailbreak the phone to create the wifi-tethering scenario, and if the bluetooth also connects seamlessly with Android based products. But, once I rooted the Tab2, couldn't I just enable the wifi-tethering app, and have the Tab2 basically connect to...itself?
1b) I use a few different apps to get decent sound. I use CM10 for my OS, and its built-in DSP equalizer app is pretty decent. It includes a 5 band eq that is good enough for me. I also like that the Google Music Player defaults its eq settings to the DSP equalizer. If you're looking for a more powerful eq, I'd use PlayerPro, with the optionally installed DSP pack. With the DSP pack installed, PlayerPro has a 10 band equalizer, and a host of other effects. I don't use the effects, but the 10 band is the only decent eq I've found on the play store. Problem is, the 10 band is only applicable to the PlayerPro app. It's not a global eq, so other apps will not be affected. For this reason, I no longer use the DSP pack. Since CM10's DSP Equalizer app is global, all sound will utilize its settings. I use PlayerPro, Google Play Music, Last.fm, and pandora, so I needed a global eq.
2) Don't worry about Samsung's website. 64GB cards work just fine on the Tab2. You'll just have to use a computer to format the card properly before you install it in the tablet.
3) I upgraded my iPhone to the GalaxyS3 before I began this project, so I can't help you with iPhone<>Tab2 compatability questions, sorry. I CAN confirm that you should be able to tether your iPhone to the tablet once its jailbroken. I used to use tethering on my jailbroken iPhone, so you should be good there. Keep in mind, it's been almost 2 years since I last jailbroke an iPhone, so my info is quite outdated.
SDB, thanks for your response. I'll be cruising around in my 2005 Hyundai Accent, so I don't have much loud exhaust to worry about =p ... A few follow-up questions:
1) If I'm not going to wire from the headphone jack to the amp, where/what am I going to connect it to? Looking for a relatively semi-inexpensive answer for this. My understanding is that some people do this via bluetooth to a head unit, but then I'd have to buy a whole new head unit, and then likely stick it in my truck/glove compartment...
2) What format do I need to use for the SD card?
3) To clarify on the inception that is the Tab2 connecting to itself... Once I root the Tab2, I'll install the tethering app. While I'm running the tethering app, won't my Tab2 detect that there is a Wifi connection in the area (which in all actuality is the wifi signal that it has created via rooting)?
4) What exactly was the purpose of breaking apart the dock...was that for power purposes?
5) In regards to the question above, I'm still having an odd mental block on how it stays powered...do you just have it wired to the ignition, and then you use Tasker to fill in the gaps?
6) Someone brought up the question of how well it works in the heat, but you wouldn't know that because it's Winter, lol...but on the same idea, how well does it work in the cold? Here in MA, it's absolutely freezing right now, and with no garage to keep my car in, I'd wonder how it reacts to the frigid temperatures.
If it helps, this is my equipment:
Kicker ZX750 amp, for my x2 12" Comp VRs
Kicker 4channel amp (I forget the model), for my speakers (which are also Kicker QDS')
Note: My Kicker "kick" was due to the fact that I could get all products direct from the vendor at a massive discount for less than $500 for everything above. Score, IMO.
1) I should have clarified. You WILL be connecting the headphone jack to the amp. BUT, instead of connecting it directly, you'll want to buy what's called a "line driver" to go in between. You'll connect the headphone jack to the line driver, and the line driver will then connect to your amplifier(s). The line driver just boosts the low level signal to a voltage that your amps will like more.
2) The format you'll want is "FAT32".
3) No device can tether and wifi connect at the same time. When tethering is activated on an android device, the wifi is disabled. Besides, you won't be tethering from your tablet. You'll be tethering TO your tablet, which means the tethering will be taken care of by your phone. Your tablet will see the wifi network, created by your phone, and the tablet will connect to it just like it would with any wifi hotspot.
4) I broke apart the doc because I had almost NO room to the left/right side of the tablet, and the doc had a really thin right-angle connector.
5) You are correct. See the wiring diagram below for more details.
6) Yeah, temp extremes are a risk, that's for sure. I remember when I lived in Denver that if it was super cold outside, my iPhone wouldn't turn on until I held it up to the heater vent for a minute. I haven't had to deal with this yet, but I'm sure I'll have to eventually.
Kicker makes pretty decent speakers, and good amps, so good job on the score. I have 2 Solobaric L5's in my SUV.
Hi, I was thinking how would you connect this to a isn interface or a computer? Would you have to take it out of the dash again?

Thanks for the quick response again. I'm starting to get it all figured out. Last few questions for now:
Do you have any suggestions on mounting the tablet in a dash? This is my dash:
I'd imagine I'd just take my dremmel and resize the opening so it'll support the Tab2 instead of the Liliput 6" monitor I have in there now...I'm at a bit of a loss as to how I want to keep it in there though. I want to be able to take it in and take it out when necessary, but at the same time, I want it to look pretty clean. Any input? I'm still trying to figure out your setup a bit...looks like you're doing a bit with velcro and magnets, but it also doesn't look like you're easily able to pop out your tablet.
And...how accurate is the GPS on the tablet? I remember using CM9 on my old Galaxy SII from Sprint, but one of my biggest pet peeve was that there was a noticeable lag and drop in service from time to time, almost like my GPS would just freak out and forget where it was going. I see that you're using Google Maps, but I had issues with both that and MapQuest in the past.
First, I'd measure the horizontal width of your current screen opening. As long as it's larger than 6.03", you shouldn't have to modify the opening of your bezel at all. It will simply be figuring out what will attach the tablet to the back side of the bezel.
