Had a discussion on this some months ago. Lots of good ideas but nothing simple available ie non OBD-x.

We now have anti-speeding laws with a margin of the equivalent of 1mph at 35mph. I'm over glancing down to the speedo and all I want / need is a projection of my speed.

Have just found this .... whooo hooo ....

Looks like it will do nicely.

Hmm...You have my Attention. Must investigate.

Have already crawled all over the net doing lots of investigating MJ.

The only lead you have to get to is that from the diff which carries the speedo pulses.

The HUD unit has a multiplier adjustment ie 1x 2x 3x etc to match the display speed to the pulse rate from the diff speed sensor. After that there is a 'fine' speed adjustment. Plus speed warning alarms etc.

Sounds simple enough to install.

Did you go ahead and order one yet?

Should be here in a week or so.

Will update forum on results.

If only the OBD-II HUDs were more flexible - those I have seen only have fixed data available chosen by the maker. Most OBD-II displays enable one to choose what they want to see from the data stream in 2 or 4 or 6 or even 8 items on the screen, out of up to 50 items coming out of the ECU. When you can compare what the 'gauges' show against what the ECU holds, you find interesting stuff - my Suby temp gauge never moves once its up to 'Normal' , while the OBD-II display shows coolant varies from 83C to 96C. Even more curious, it shows that in lower ambient temps (eg 15C), coolant will readily run up into the low 90s, but in warmer ambients (mid 20sC), its usually held mostly under 88C.

I've been looking at the Garmin HUD that incorporates a GPS as well. Still waiting to read any reviews from people already using it.

any old smartphone and a free app?

they are typically not very good in bright sunlight, but i suppose you could find a small piece of clear film to place on the windshield to help, and max out the brightness of the display.

i tried the Torque app in my Evo X with a bluetooth OBDII dongle, and was pleasantly surprised to find that i was getting 46mpg! ~16-17mpg in real life
some functions work, some not so much.

Yeah, the cool thing here being that you can pick up an old cell phone on eBay for lunch money (under $30, all day), and you don't have to have a cellular subscription to load apps, just a wifi connection. It also doesn't require a cellular subscription to display the speed.

Just a thought for someone wanting to give it a try. I'm sure there are a lot of us who have old smartphones in a drawer at home.

I've got a pile of the things...

I recall reading up on this Garmin unit, however the GPS feature I believe only works when paired to your cell phone is that correct?
