This is an alternative to the oem rpd available in the 09-10 SS models. The Amped Autowerkz RPD allows you to retain the factory storage compartment and have a rpd style display. This gauge works with ALL year HHR’s as well as both SS and non SS cars. The gauge is included as part of the kit. The gauge is based off of an obd2 scan gauge and can display a range of different parameters along with reading and clearing DTC’s.
