    Parking, Reverse, GPS & USB installation on aftermarket audio system?

    I have a 2012 Mazda 5 and getting a JVC-KW-M845BW along with the PAC RP4-MZ11, Metra 40-HD10 Antenna Adapter, and Metra 95-7521B Dash Kit to replace the factory unit (which I have already replaced once on my own). JVC has a couple of wires outside of the harness. Given that I am not very familiar with installing car audio systems, any tips I can get would be a great help:

    1. JVC Parking brake switch/indicator wire
    2. JVC Reverse sensor wire
    3. JVC GPS unit - how to route the cable from behind unit to outside on the dash?
    4. JVC 2x USB - how to route the cable from behind unit to outside on the dash?
    5. JVC Bluetooth mic - how to route the cable from behind unit to outside on the dash?

    I have been told by Crutchfield that 1 & 2 are located somewhere near the cabin filter area, but I am not sure where exactly. For 3, 4, and 5 I am thinking of drilling holes/slots on the Metra dash kit to get them out. Any alternate suggestions since I see no way to get the cables from behind the unit to outside? JVC wiring diagram attached. Thanks in advance.

    Just for those looking for this information, I eventually figured all of this out

    The parking brake switch & reverse sensor wire are both part of PAC RP4-MZ11 harness and so you won't need to run lengthy wires to other spots in the car. My 2012 Mazda 5 does not have an amp so I had to cut the RCA plugs off my PAC RP4-MZ11 and hook them to the stereo speaker wires directly. I ended up putting the GPS unit right in between the two air vents underneath the dash and above the car audio unit and it works just fine. I was able to route the cables for both the USB and bluetooth mic through the driver side without having to drill holes. A bit of work but wasn't too bad. Only the Metra dash kit with plastic hinges was a big disappointment; will snap very easily if you are not careful. Android Auto wireless only works with my older Pixel XL phone (currently using Huawei Mate 20 pro), but given that I had to use a cable for JVC Weblink app, I just use the wired android auto.

    Good info!

    And there are ways to slave another Android device to the head unit and then run a custom APK to enable your main phone to use the slave phone as a wireless pass-through. Unofficial wireless Android Auto.
