I've documented some of the work I've done installing an iPad mini into my '04 996 in several threads on a few different forums... I'm putting the information here in its own thread as well.
Sorry if it seems a bit discontiguous, much of this is cut and paste.
-----------
Here's what I'm doing:
Relocate HVAC to lower slot in lower center console.
Relocate head unit to upper slot in lower center console.
Replace head unit with Pioneer single din with USB input and enough charging current to keep iPad mini operating properly.
Custom mount mini in upper dash.
Modifications to horseshoe bezel and cup holder trim only. Can be returned to stock easily by replacing $60 bezel.
Mini will feed into pioneer stereo, then to upgraded speakers in dash and rear.

On the hookup, you could eliminate the head unit and go directly to the amp, but there are several considerations...
Head-unit solution:
A top of the line Pioneer 1Din head unit (DEH-X9500BHS) is only $182 on Amazon.
It has dual USB inputs with adequate charging current for an iPad mini, three sets of high-voltage RCA outputs if I want to drive an amp, HD radio, Sat-radio ready, and adjustable illumination color so I can exactly match the OEM amber lighting. It also has full bluetooth integration with my iPhone for calls.
A volume KNOB rather than some slider is very nice.
Built in amp is adequate for my current needs
Easy to mount into one of the existing DIN openings.
No head-unit solution: There are various ways to do this, but they all have some limitations. IMHO the BEST way would be
iPad mini
iStreamer digital-analog converter (DAC) ($230). This will allow you to bypass the relatively low quality DAC's built into the iPad to get a higher quality signal and simultaneously charge the iPad.
Audiocontrol three.2 equalizer (~$300), fed by analog output from iStreamer. This will provide a real volume control knob as well as a front/rear fader (though still no balance control). 1/2Din form factor, so it will need a bit more custom work to install.
Four channel amp. On the inexpensive/small/light side, something like the Fosgate punch PBR300X4 ($150) would be fine.
My original intent was to not use a head unit, but as you can see, it might seem simpler to eliminate the head unit, but it actually requires more stuff and is significantly more expensive to do correctly. It just didn't make sense with all the great low cost USB input head units now available to try and work around it. You could do nothing more than take the headphone output of the mini and use a headphone jack to RCA cable and run it right to the amplifier... It would likely not have sound quality, and quickly adjusting the volume is difficult. And it *still* would cost as much as a decent USB input head unit... ----------- I function tested everything previously with the head unit and HVAC in their original upper position and the iPad mini just temporarily mounted to the lower console. Pandora, Slacker, Waze, MotionX, Harry's Lap Timer, Safari, Google maps, Apple maps, accu- weather all work great. You can even make phone calls if you want without a cell phone using a skype account. Inbound as well, but it takes a bit more work. One of the things I've been waiting on is the IOS/iPad-mini jailbreak which was just released today. The thing I really wanted jailbreak for was to eliminate the 'lock' slider and have the mini immediately go live to the last app in use when the ignition is turned on, and immediately go to sleep when the ignition is turned off, just like it works with the smart cover. Simple enough, but impossible to accomplish without jailbreaking the device. The jailbreak should also allow me to use the less-expensive generic OBD2 bluetooth devices to feed data to Rev, harrys lap timer, etc. -------- I just got out to the garage to do a final test fit. Everything seems to fit perfectly, though I still need to purchase the lower HVAC trim bezel (996.552.339.00-01C). Sorry for the crappy garage-at-night photos. I'll get some better pictures once everything is finished and cleaned up, but this will give you the general idea... ----- Visual notes on the cup holder could be retained... ----- More details on the horseshoe bezel modifications... After modifying, the iPad is sandwiched tightly between the front bezel and the radio support bracket.
