casperboat Posted October 1, 2015 Share Posted October 1, 2015 The speedo in my old landy reads wrong, it's slower as I have the wrong diff fitted, but it also wobbles quite a bit, so it's difficult to tell what speed I'm doing, though it's probably slow... I've looked at GPS speedos as they fit them in some racing cars, but these are £78, the head up ones, which are cheaper, I'm told are not very good. Been looking on ebay and there are loads of satnavs for under £30, but I can't judge whether any would give a clear figure on them of the speed.. Has anyone any recommendations.. Thanks.

ejparrott Posted October 1, 2015 Share Posted October 1, 2015 If it's a series, pull the rear prop and make sure the output shaft nut in the centre of the flange is tight. If not it'll allow the Speedo gear to slip, there's no key to drive it. You could also try oiling the Speedo cable. Quote Link to comment Share on other sites More sharing options...
Lewis Posted October 1, 2015 Share Posted October 1, 2015 I went through this a few months ago, maybe last year. There was a thread in the international forum. In the end I bought a £2 suction mount phone cradle for my iPhone and used a free app on that. It was a good solution http://forums.lr4x4.com/index.php?showtopic=89216&view=&hl=&fromsearch=1 Quote Link to comment Share on other sites More sharing options...
casperboat Posted October 1, 2015 Author Share Posted October 1, 2015 Ok, just read through that thread.. You didn't seem to have much luck. I wasn't after a round speedo, but wondered whether a standard satnav would show the speed, in any form that I could read while driving. The best option so far seems to be a gps speedo from Demon Tweeks at £79.98.. Quote Link to comment Share on other sites More sharing options...
Scotts90 Posted October 1, 2015 Share Posted October 1, 2015 Can you not borrow a nav unit or use an app on a smartphone to see how accurate (or not) your existing setup is? Mine is accurate up to about 40 then starts to under read (47 is 50, 56 is 60 etc), once I knew what it's "real speed" was I didn't need to use the gps anymore. My main concern was the large stretches of average speed cameras we have up here. Quote Link to comment Share on other sites More sharing options...
Arjan Posted October 2, 2015 Share Posted October 2, 2015 Basically, any old GPS unit will have a screen where the speed is always shown. Some will hide it when you have it working on guiding you. But borrowing one to make sure what is shown when should also work well.. Quote Link to comment Share on other sites More sharing options...
casperboat Posted October 2, 2015 Author Share Posted October 2, 2015 Unfortunately my family is so far behind in tech terms that non of them have a satnav and my phone is an old brick which doesn't even take pictures or have internet access... My friend's cars have satnavs built in, so can't be borrowed. Guess i'll try and find a cheap one to try. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted October 2, 2015 Share Posted October 2, 2015 Well, if you are someone who has chosen a low tech approach, then I would suggest one of the recognised brand leaders, from a bricks and mortar outlet, like a Tom Tom , or a Garmin. Reason being is that they are designed to be simple enough, and sturdy enough to cope with non-tech levels of care and use. You will need to power them, so assuming you have a 12v vehicle, you'll need to install a 12v supply point, like a cigarette lighter socket, to ensure that they work. You can get 12 plugs that connect to the dashboard jacks, and should be able to connect a cigarette socket on a wire to that plug. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted October 2, 2015 Share Posted October 2, 2015 I'd recommend a Garmin. I've had a TomTom for donkeys years, waterproof bike version, I have to pay for map updates. New Garmin recently came my way, lifetime free map updates. That point alone makes it more sensible to me. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 2, 2015 Share Posted October 2, 2015 Have to say, have a bike Garmin GPS computer, quite old now, amazed at the support for it though, very regular updates for software on the mac and for the device. Quote Link to comment Share on other sites More sharing options...
