1) Di everyone's audio work straightaway without having to splice anything? We had little for sound until we jumped the factory black/red amp power wire to the blue PX6 amp wire. Everything was way too loud until I found the sliders in INSTALL SET.
3) Is anyone running a USB hub to allow a DVR and an external Hard Drive AND the iphone in the OTG port to run the fake Chinese carplay app?
1. Mine worked fine right out of the box in my 2006 'LX -- no splicing. But others here have definitely had different experiences, depending on the model year and whether it's an LC or LX.
3. I tried using a USB hub. It worked fine with a thumb drive, but I couldn't get it to work with my external SSD. I assume I'd need a hub with a separate power supply if I wanted to use the SSD with it.
