Also on my car, in the factory gauge cluster there are 3 gauges not working and i am ready to make a custom cluster simplifying it and de-cluttering the A-pillar.
They offer a electronic sender version or a GPS version (Has turn indicators and high beam LED's too!).
I know the installation will be much easier - power, antenna has good view of the sky and the dimmer/illumination to be hooked up.
Only problem i can think of is when being in a built environment and there is limited/no signal. In NZ there arent too many tunnels so shouldnt be too much of a issue.
What do you all think about these and if you want some let me know - i could organise a group buy.
At this stage, i'm keen on the Speedo, Tacho, Fuel Level, Voltage and maybe water (i have the DEFI water but in the dash might be more cooler-er!)
Gauge faces are customisable and can have ANY logo you want including TRD, SUPRA, TOYOTA, MR2, GT-FOUR etc and these are mostly on file too.
