We still have what I think is the factory car head unit in our 2007 Mazda MPV, it's still in Japanese language but plays the radio and CD's. It also is the screen for the reversing camera.

Just back from a family holiday away and found (while fine for those trips around town) it wasn't the best for long road trips for tuning in new frequencies etc.

Looking at changing out the headunit for a new one with similar features but want to know if the current reversing camera would work on a new headunit or the camera (or wiring connection) would need replacing also?

There is a good chance that you will be able to keep the existing reversing camera, but frankly you won't know until you get stuck into the new head unit install.

Reversing cameras are very typically NTSC, so the head unit needs to be able to work with that signal format type.

Are you one of the MPVs with a side camera also, on the passenger side mirror?

If so, there may be more to this...

One stereo installer said it was 50/50 chance, another said 80/20 chance
It took him 4 hours but he got it going (07 Honda Stream)

We did an install on a similar car recently, couldn't work out the wiring after putting a meter over them, so just copied the install from our car and it worked.

Chances are that the reception issue you had is due to a poor quality band expander. If you replace it with a high quality one you might not have the issue.

Ours only has the back reversing camera, no side one.

The band expander itself appears fine, didn't have bad reception issues, it was that it's not the easier to change stations and save the presets tats the issue.

Anyone know what the actual connection is for the camera? Something common or particular for our model of headunit and camera?

Usually RCA. If yours is Mazda OEM, it may be part of the wiring loom for the stereo. You won't know till you pull it out.
