Wondering if anyone in here is using one of these? My car is gonna stay street as it's my DD, so I'll be keeping my touchscreen NAV. This seems like a pretty interesting alternative to a-pillar or dash gauges, especially since you can add in a component to wire in up to 5 sensors that aren't part of the OBD port. Anyone using it that can give some intel?
