air gauges in head unit??

does any one know about this?? i heard that some flip out head units can display air pressures. is this true? if so which ones and what all do you need to make it work.

bump

bump again

damn, i had one that told me battery voltage but if you find one im gonna buy it maybe!

yea me too!! i can't really find out alot of info, but i think the ones that tell you engine info will tell you air pressure. you just got to get the right stuff to hook them up.

I know pioneer's tell you the engine stuff but i never saw air pressure.

theres a new kenwood double din that you can hook your switches up to.. but NO

there are NONE you can hook up an airline to

i think he meand a digital pressure guage kinda like the dakota digital guages and such lol

I so wanted to do this on my benz but on the gauge cluster display, how sick would it be to go to a display with the steering wheel controls and then use the steering wheel buttons to raise and lower? then whenever you are off that display you are at ride height. If I could have found someone to do it I totally would have.
