wrong password for connected cam and iPhone

Hi.
New to the forum.
I have tried to connect my IPHONE to front camera by following all the instructions, everything goes fine till, as instructed I put in the default password on my phone, after doing this it keeps informing me its the wrong password, I have tried resetting the camera ( as instructed ) I have also tried various other ways, including different password, but still no joy.
My phone is up to date and has ios 10. Anyone else had this problem and if so how did you rectify it.
Regards

Just in case anyone else has this problem in the future, I am about to answer my own question. After many weeks of trying and following all the instructions on trying to get the connected cam to work with my IPhone I gave up
.( even after great assistants from Citroen customer care )
As I already new, I had to delete the previous owners password, but no matter how many times I tried this in the past it would not happen. I tried again a week ago and for some reason this time it worked, and the previous password deleted.
After that it was a simple job to connect camera to IPhone. So the moral of the story is keep trying.

The default password in my manual (and the online version I looked at) is given as ConnectedCam. This did not work.

However ConnectedCAM did.
