    Help me design my carputer for my Porsche 911 (997) Cabriolet

    Hi, I'm looking for help in designing my carputer system. I have a 997 Cabriolet that I got with no options other than a bose sound system (I can barely afford the car let alone the $4000 nav/com system!!!) There is a "basic" onboard computer in the car already, but this is not an open system, and options are expensive. I want to install a carputer that can:

    - Play mp3s, dvds, ...
    - GPRS voice navigation
    - internet (via bluetooth phone)
    - Radar detector integration (is it possible?) to provide complete hidden system
    - Integrate into car audio system

    My biggest dillema is that I don't want to change the look of the car. The car already has a LCD screen which is used as an interface for options I have installed (basically the stereo and some internal/external temp info and a trip comptuer). I'd like to replace the LCD with a touch screen to use as the interface to the computer, but I'm concerned that some functions would no longer work (like the Sound button which lets you change the EQ and ballance settings). Please note that there is a 3 line LCD in the dash that displays basic functions (like radio station/CD track- please note the CD slot).

    I was therefore hoping to get some installation advise/ideas. Is it possible to install a touch screen that could be "switched" between the PC and car computer?

    Can some of these buttons be reused (for example, when I press NAVI, it switches between the two).

    I use PCs and Macs at home, what is the best integrated system out there? Is it drivesoft (HW and SW), or a specific type of PC with mediacar (looks dead) or DashPC?

    Attached is a picture of the dash:

    Thanks in advance for your help!!!

    How big is that screen? Doesn't look like a 7"

    Not sure about the LCD size- may be 6.5"- I'll check tomorrow.

    Here are some pics of the (crappy) UI- may give a better perspective.

    I think you'll find the PCM is a solid unit, all buuilt in to one big double-din box, I doubt you'll be able to reuse or replace the screen to be honest. You can however pull it out but then you'll need to look into the alternate bezels.

    I've seen a couple of Boxsters with Lilliput screens in them, they fit quite nicely in the double-din but this 997 dash is a different layout to the original one, what year is the car?

    To look at pulling the PCM look at www.renntech.org there are guides there on installing PCM so the reverse will allow you to remove it. What features other than audio are provided by the unit that you'll lose?


    I think you'll struggle to be honest, you don't have anywhere to install other than where the PCM is and I think you'll lose a lot (including value on the car) if you remove it.

    The orignal dash basically had four din slots, the top two would fit a 7" almost perfectly. In my car I want to keep some storage so I'm putting an in-dash in one of the spare slots (I have a Boxster).

    Oh also, if this is an 03 or newer and it's like the Boxster it will be using the MOST fiber-optic connection between components. This integrates with the CAN bus and basically prevents you easily exchanging the head unit. The concept is good but the practicality is not. If the PCM has the amp built in then you'll need a new amp as well as a new head unit (or Car PC).

    For radar get a V1 with the remote display...

    Hi, the current LCD is 7". The car is brand new ('05).

    It looks like the entire PCM would have to be removed... has anyone done this with a 997?

    What "complete" system would you guys recommend?

    The PCM will pull right out, the issue is what you can replace it with that will integrate with the car. Assuming the PCM is hooked in to the CAN bus the car computer will probably need to be told it has gone as it is tied in to the entire system for security (it will not work in another car if stolen).

    Hum, is there another place that the PC screen could fit? Like in the glovebox (where the CD holders are)... that way I could potentially integrate it in the PCM although there doesn't seem to be an Aux input...

    You could mount one on a flexible stalk or in the glove box, if it is the usual Porsche 1 Din CD Holder you may be able to replace it with an in-dash screen.
