I would be very surprised if your Ford steering wheel controls were compatible with this head unit.

Depends on whether your automobile has a standard-sized stereo head unit or a brand-specific OEM unit. If standard, then you should have no problem with making the swap. If non-standard, it may require an add-on faceplate surround to achieve a decent finished appearance. If you ask your local Best Buy stereo installer crew (no, I'm not on their payroll), they can give you a specific answer after just a single quick glance at your car's dash. This Sony unit is a the standardized size that is considered a universal replacement. Good luck.

Otherwise, you might consider going to the Sony site to determine actual specifications -- size, etc.

Depends on whether your Lancer has a standard-sized stereo head unit or a Mitsubishi-branded OEM unit. If standard, then you should have no problem with making the swap. If non-standard, it may require an add-on faceplate surround to achieve a decent finished appearance. If you ask your local Best Buy stereo installer crew (no, I'm not on their payroll), they can give you a specific answer after just a single quick glance at your car's dash. Good luck.

I'm not a techie, and your question veers into tech territory. That said, radio signals everywhere use receivers and transmitters; you just want to double them up to use your CD changer on an empty frequency. I suspect that it will work with this Sony stereo head unit. However, I wouldn't expect any of the CD track info to make it through the transmit-receive process. And I suspect that you didn't have it before, either.
