I haven't fully completed my installation yet, but at least with the RAV4 sitting in the driveway everything seems to work including playing the DVDs.
It's because the gyro inside will sense your movement. That's how it tells your speed. There is other bypass for that has well
And any wire will work thin speaker wire.
18 awg primary wire, your not passing much current through the relay so no worries.
