I have changed radio from app radio 1 to sphda100

All work's

But when ipod connected an i use Navgate app radio sometimes show me The Same MSG of rear camera "Image...."

And many options on setup menù are gray....

I have connected The GREEN whith wire on ground ( it is a European radio)

If i disconnect it The setup menù return ok. Nothing for The alert MSG.....

I'd imagine you've grounded the reverse(rear) camera switch rather than the handbrake(parking brake) switch.

Or the reverse/rear camera wire(White/Violet) is rounding from the cage or elsewhere

No the wiring it' s correctly!

I have See on youtube that someone have used one relay, because the lock function whith one variation of state and not with a continuous signal.

This saturday I try do it.

Usually you don't have to do that on the European model, Mine is just grounded and I've never gotten any warnings.

Did you update the firmware by any chance?

No i haven't update it! How it's possibile to check The installed software version?

Not sure how you check the current version, I'd imagine you can find out in the settings menu.

I installed the US firmware by mistake and was getting a funny message about the parking brake, I immediately installed the correct firmware and all was back to normal.

For The Parking brake ok the wire on ground!

Now function all correctly.

But the problem to rear cam MSG sometimes continue, it depend:

If touch the icon on the top right to main windows, and close the MSG, it appeare sometimes when use other functions, radio, iPod, ecc.ecc.

For eliminate the problem it's necessary on the setup mode put off the rear camera function and reselect the correct function!
