When upgrading an existing single tone car horn to a dual tone how complicated is the extra wiring?
No Simon, that won't work.
What you are suggesting is wiring the two horns in series, and that halves the voltage so you would have two horns running on 6 volts. They need to be wired in parallel. A lot depends on how good the horn's relay is and if it can handle the load of two horns. My thought is that it probably will as many vehicles already have twin horns. The positive lead from the relay needs to split and go to the positive sides of both horn, and the negative of the horns to grounds. Ideally, two relays, two horns, two grounds.
Look at the YouTube video of the guy that added a huge locomotive twin air horn. It is funny as he goes looking for jay walkers! If I remember he had to install a second battery for it as the load for the air compressor, made the engine stall.

My xdvd210 has no video signal when i turn on my headlights
I just got done fixing that problem on my 04 toyota camry. All I did was disconnected the orange wire. Idk how your harness is like, but mines I accidentally hooked that orange wire thats from the radio to an orange with white stripes to car harness. So as soon as I disconnected that it works with my headlights on. Hopefully this will help.

Check all wiring/connections, fuses, etc. and don't forget the one on the back of the deck itself!
