Has anyone on here thought about installing a CarPuter in their Audi or even actually gone ahead and done it? At heart I'm bit of a geek so the thought of having a PC in my car is well, quite exciting (I need to get out more!). I'd toyed with the idea of simply changing the HU and getting a radio transmitter for my PocketPC but I soon dropped that idea after getting berated (on here!) for it being a stupid one (it was!). The other thing that put me off changing the HU for an aftermarket one is they all seem to have comprimises one way or other... Some have features that are 'missing' on others and vice versa. Then there's my other pet hate... HU's that are the automotive equivelant of Blackpool illuminations! After hearing about CarPuters for a few years, but never really looking into it, it dawned on me that having a CarPuter would solve the problem of choosing a HU (that I'd probably never be 100% happy with) and would satisfy the inner geek in me! Having access to a 200Gb hard drive with my entire library of audio and films (stored as DivX files), DVD Player, TV, SatNav, and lotsa geeky stuff would be very cool! I've been looking at a Lilliput motorised VGA screen that has a built in radio tuner tuner, PC video input and an input for a reversing camera. As far as I'm aware its also got 2 audio inputs so I can channel the audio from the PC and also an existing roof mounted DVD player to it. Incidentally the roof mounted DVD player has a video input so I can route a TV-Out video signal from the PC to it also. The benefits of this is that if a film is being played from the PC it can be viewed on both screens (with audio out the car speakers) or if a film is being watched in the back the sound can still come out the car speakers but I retain volume control from the front while having SatNav or something displayed on the in-dash screen. I also want a DVD drive in the glovebox, as well as a couple of USB ports for plugging in portable HDs or flash drives. I know I need a power supply that boots up the PC when the ignition is switched on (and has crank protection, to stop it from rebooting when the car is started) and shuts down (or hibernates) when the ignition is switched off. Is there anything else I should be on the look out for? I don't plan on changing the speakers for the minute (one step at a time!) but, as AndyMac has said time and time again, I will run all the speakers from the HU instead of relying on Audi's puny little Amps. However, how do I go about wiring up the (standard) rear sub if I run all the normal speakers from the HU? Any thoughts, advice or inspiration anyone has would be greatly appreciated! Ta!
