Hi dude....
....not tried the G-Tech, but hear good things about it.....
...I settled for the Race Technology meter.....it's quite impressive for such a small box....
....the lateral G feature and G-circle is cool too.....a bit like the R34 v-spec display.......
.....but about £40k cheaper....
....as for installing, put the batteries in, and fix in the horizontal to yer dash.....
...they even supply blu-tac, fer chrissakes....
....quite close to the real thing when run side by side at the pod...
Take care folks,
JonB
Peace, Love and Horsepower...
