hi there folks, just wondering if anyone out there has bought and installed an apexi rev/speed meter. i kno the Zs have so many guages already, but im interested in this because it has an optional g sensor that can calcuate ur car's power and so forth...since i have the base model, i have nothin in the navigation compartment, and i figured this will look nifty in there. if anyone has this installed do u have pic i can see? and is it worth buying? $229 for the meter and an additional $55 for the G-sensor..thx
