my series 2a 88 '69 speedo's needle fluctuates a fair bit and as i have smaller tyres fitted which affect the gearing i didnt want to be over or below 30mph in traffic etc ,
i bought something similar to this gizmo for £15ish,i hooked it up with a poundshop phone powerpack and it does the job spot on,it takes 2 or 3 minutes to link to the sats and uses hardly any power and has a clear display, i have checked it in my van and its accurate,,
just a heads up,

Thought GPS there was time-lag hence the rule of average apply. sadly older Speedo have to be calibrated but even then it a plus minus. Digital speedometer possible more accurate.
 
Unfortunately an MOT fail, or if MOT exempt renders the vehicle not road worthy.

Edit. Apologies, read this wrong. Thought you had a non working speedo and fitted as a replacement.
 
A working speeds is not an MoT requirement. The tester needs to get a mileage figure from somewhere, but the speedo itself isn't part of the test.
 
Agreed, the manual leaves a lot up to the tester in terms who opinion and speculation.

I've not decided if it makes it easier or harder!
 
at a rough guess i havnt had a vehicle speedometer checked at an mot for over 25 years and that was just them lifting and spinning the front wheel of a motorbike,i dont think my vans speedometers have ever been checked in 40 years, i presume if the mileage had stayed the same from the last test it would be a signal for them to check,
this digi gps one is great,it doesnt lag and is suitable for whatever tyres or diffs are fitted, not to replace your speedometer but to compliment any tired,50 year old one that is not 'paired' with the gearing/ratios of the drive train.

I stand corrected. Although 'If a road test is not necessary, you should only reject a speedometer if it’s clearly not working.' is rather vague, and my tester has obviously decided it wasn't clear enough! :) I was told as long as they can get an odometer reading, they were happy. Although that was a few years ago...maybe someone spotted the obvious omission and the rules have been tightened (a bit) since then.

Of course, most phones can act as a GPS speedo, with suitable satnav or specific speedo apps, if you have a phone holder. The specific units are a lot neater, though.

Do you have a linky to one you got? Thanks.
 
i bought mine off ebay(u.k seller) and the one i bought is no longer available,i looked before posting the thread, a search for 'gps speedo' will find other sellers.the picture was from amazon iirc
some are round shaped so i suppose they could be hard wired in but i use mine on a greeves scottish m/cycle as well as the land rover hence one that can be dash/handlebar mounted was my choice.

An alternative to a GPS Speedo is to use a tablet computer that has a GPS chip inside. Then choose a suitable app..
I use a tablet as a road navigator and another on my sailing boat to display speed, compass, and race time.
 
The comments about mileage are interesting.
Browsing the MOT history of our daily (non LR) revealed two consecutive annual tests, prior to our ownership, where the mileage could not be read ( digital ribbon fault) but that was only listed as an advisory.
