Do GPS's have speedo's on them and is it all GPS????????????????

Yes they do. Its a good way of checking your speedo.

I fitted the Truspeed unit and it is excellent - cost just over the $200 mark from memory but it allows me to run 2 set of tyres (i only run one just now) and is incredibly accurate once fitted and calibrated against a GPS speedo.......worth it IMO as I hate not knowing what speed i'm doing.

Aye, Mick

P.S. I tried another way to get round paying thr $ but no other way in my D2.

Truspeeds are for electronic speedos, and I'm pretty sure the D1 has a mechanical drive.

GPS's do have speedos in them, but you can't use them as a primary speed device according to the RTA because they dont work in all conditions.

but... I don't know the answer to your question.

Hi lowbox,

Long time no hear.

265s are about a 32" tyre aren't they? All I did with my old Disco was fit a Defender speedo drive.

If you don't mind a bit of soldering, Jaycar sell a Speedo Corrector kit for $49.95 and a Digital Speedo / Speed Alert for $64.95

yeah they're 32's compared to standard 29's. about 11-14% out so enough to get tickets...

will have to dig out workshop manual to see what drives the speedo...
