I'm thinking of upgrading my H/U to a Boss Double Din:
I'm curious as to what specific harnesses I will also need to make all the factory features work with the upgrade. It says it has "Built-in steering wheel control settings will connect directly to your vehicle" - Is this true or will I need a specific harness? I feel like I'll be needing at least one, if not more, harness to enable all factory features to work with this H/U. I have sync, but this H/U has two USB ports, so I'll be using those rather than the factory one. It's going to go out to an amplifier, if that makes any difference in terms of what harness(es) I will need. The important things are the buttons on the wheel - I love those and would really enjoy to keep them all working.
