If interested, I use this for a "HUD" to more safely watch my revs and ideal shift points when in manual mode. The tack in the dash is silly. Not super sexy, however it has been a positive conversation starter and more than gets the job done

I've been pleasantly surprised by the HUD Im currently using. Dumb name, but it has numerous functions, layouts, statistics, etc. while still being inexpensive. Does the trick if you're not racing.
