Metra CHTO-03 in Jeep Patriot

Because my 2009 Jeep Patriot had the Sun and Sound package, it also included a factory Boston Acoustics amplifier. The amp and speakers are pretty good, and sound decent even at higher volume. The problems start when you try to hook up that factory amplifier with an aftermarket deck. I’m not sure how tough it is to connect the 3rd party amp, low speed CANbus, get 12V out of the whole ordeal, and connect to your deck, but the Metra Axxess CHTO-03 did it just fine. If you’re looking for a steering wheel interface, the ASWC will do the trick for you, and is pre-wired in the CHTO-03 loom. Make sure that the aftermarket deck that you choose has front/rear RCA pre-outs, as it’ll make it a lot easier to interface with this device. There is a gain control between the RCA’s and whatever it spits out to the amp and I did have to tweak the setting to get back the volume that the system was capable of from the factory.

The Metra CH-03 came with factory connectors, so the only thing I had to solder up was the connection between the CH-03 and the aftermarket deck. I basically saved the $15 that I would have spent on the factory connectors and I got the interface into all that proprietary Chrysler goodness.

The CHTO-3 also had a few NAV related items like providing vehicle speed, park brake, etc, but I didn’t use any of them. Might come in handy if you’re thinking of installing a 3rd party gps nav into your Jeep Patriot or Compass.
