What with a increasing enthusiasm for tighter speed monitoring on our roads and the inevitable inaccuracy of a T9 cable-driven speedo in a Morgan, I'm thinking it might be wise to join the ranks of those who have fitted a GPS Speedo, especially with a Scotland trip coming up.

But a quick perusal of Amazon seems to show (a) a bewildering variety and (b) that they seem to be pretty large, so over to you guys.

I want something large enough that I can see the digits at speed (obvs), but small enough to mount in the eyeline of a Trad without obscuring too much. Extra bonus points if it can do some trip logging, even more bonus points if you can download the data for analysis.

TIA

To show how cheaply they can be had I've just ordered this from Amazon - £28.49 delivered



It displays trip, odometer, real time, running time, altitude and of course speed, max and average. Quick detach from handlebar mount for recharging. It will be used on my Guzzi which doesn't have any speedo.

Sorry if this is stating the obvious, but there are two different types of HUD mini speedos out there ... one reads the GPS and one the vehicle's electronic speedo signal ... they look alike ... having nearly bought the wrong one for my old (pre-electronic) car in a fit of enthusiasm, it's worth reading the ad carefully

and a third type that reads GPS speed from your phone and bluetooths to display.

Didn't come across that type when I was looking Richard ... presumably to soothe those among us who can't imagine doing anything that doesn't involve their phone! 🙂

Why not just use a SatNav, probably more accurate than a cheap Chinese GPS. Remember you do need to be in an area that gets good Satellite reception or you can get lag or drop out.

Because my sat nav is too large to have close to my sight line. I want something more discreet.

I went the 'cheap Chinese' route (because I hope that it will be a temporary fix while I get my main speedo to work with wonderful accuracy in spite of the cable currently being incompatible with the Type 9 5 spd box 🙂) .... my Defender has a spot-on accurate mechanical speedo (measured against various GPS and roadside speed warnings) ... so I tested it out by fitting it in the landy ... was surprisingly accurate and except for taking 30 secs to 'boot up' initially seems remarkably stable here in the NE Scotland.

Having an idea what revs correspond to what speeds as a temporary fallback for if you do get a drop-out might be reassuring.... though I guess in your case you can temporarily forgo the HUD in favour of the main speedo if that happens

I believe TBM has used one in his Morgan for some time, so maybe he can give us a 'long term test' report?

I was going to ask a similar question regarding the purchase of a GPS speedometer. Unfortunately, all the ones I came across, claimed to be “head up” display reflecting on the windscreen. I would prefer something simple that I could see.
