I think with a little jiggery I will be able to mount a iPad mini in the space that my clocks live, there is room to push back the original clocks to gain the space needed and continue the odometer running, all dash lights can be remounted no problem and of course a iPad with a gps will have a speedo app. Quick measurements state that it can be mounted with out obstructing the fuel or temperature gauges

Few benefits include sat nav, music management, custom clocks\speedos, plus the ice factor while stopped

I know carputers are legal but not sure of the ins and outs of it all.

What I was wondering is the legal side, by mounting it in the dash area instead of in the centre section,

Pretty sure the original speedo must be visible and working?

Yes that's correct, the original speedo needs to be clearly readable.

Oh that's a shame,if it must be the original clocks then no up grade is ever legal

it's a whole lot more complex to do it in the centre and make it look factory fit,plus it's got a lot to do with the spedo and sat nav,

I think I can keep the original speedo running just behind it all. Don't the more flashy moderne cars run gps based speedos and fully interactive dash which it not far off a tablet device integrated in to the car

Are you sure?

The vehicle needs to have a speedometer, but I don't believe it needs to be the original. It's very common for bikes to have different clocks to the ones from the factory. As long as it always displays your speed it should be fine.

On that subject you'll probably be better off with an android tab where you have far more control than an iPad.

My wife's the tech in our house so Im well behind on the tech, what's the difference , plus Apple has infected my house hold so would make it easier to pair all our devices

I didn't know there are cars with gps speedos? I thought you had to take the speed from one of the wheels?

Android lets you automatically run apps on startup, so your "dash" comes on with the car. You can't do this on a non-jailbroken iPad.

Could this be done on a jail broken version

Yes that solves that problem quite nicely, does this work though basically being plugged in and not running a battery.

Any particular device which would be good for this, max size is screen height os 137 mm

See now I'm lost, can or can't this be done

Yes, on a Jailbroken iPad you can have it auto-start apps.

I don't think there's a jailbreak for iOS 7 yet though, so you would have to stick with iOS 6 or older.

Just depends on the legal side of where u can or can't replace the clocks

The speed will be wrong, GPS is not perfect as there is a time delay, especially if you are using an APP.

 

You can replace the clocks but it needs to be a speedo, not a device like an ipad with an app

GPS is going to be inaccurate/not work in tunnels, underground/multi storey car parks and narrow streets with large surrounding buildings. So I doubt anybody uses GPS for speedos.

Many thanks lots of replys.

The basic answer is no,

But to continue the debate,

my garmin cycling computer uses gps to record speed arucutly even when it has signal drop out and so does the one in the car, are thy not working on the same system that all gps must use, ie satellites

My satnav has a tunnel mode where it guesses the speed and location through tunnels based on your speed when you enter it.  That's what I assume yours is doing.

As above, most guess based on previous speed and use of microphones and/or accelerometers but these are easily fooled.

 

I've been stationary in one of the Birmingham tunnels yet my HTC told me I'd carried on at 40mph. and stopped my location a few miles away waiting for a signal. Hence why cars dont use them and go by the wheel rotation.

they will most likely doing as suggested above. 

 

GPS, as I said earlier, has a time delay. Those satelites aren't exactly close. This time delay causes a slight in-accuracy in the speed reading. The same time delay causes your satnav to stutter slightly, especially when its just turned on

I've seen it done in a Fabia Vrs. It was a lad called mason

GPS is based on time differences. IIRC the satellites send a time signal and the differences in the delay between sending and receiving for different satellites is how you receiver works out where it is.  Non military GPS has inaccuracy built into the signal which accounts for the vagary in location.

 

Commercial differential GPS systems use fixed base stations and/or radio signals to correct for the built in inaccuracy.

My pals Volvo just passed its MOT with no speedo. Tester said it wasn't required for the MOT and put the miles down as zero on the certificate.

along that vein Korban's looks good in the centre with the binacle

that's definitely a fail now, it changed in Jan 2012 if I recall, the speedo is now a testable item and furthermore the illumination has to work too, the other the test item that came in on the same date is the trailer socket and something else too that escapes me now..

The way I'd do it is to use an android tablet, a obd adapter and the torque app. The app shows all engine data, a gps speedo AND the reading for the original speedo, so no problem with lack of signal

This makes a lot of sense auto power up direct link to the car, just no pairing, but u can't have it all

Seems android it the way forward and will be cheaper ,
