please visit this thread for question 1 The most recent post will likely answer your question
I do not understand the nature of question 2 If it is the new transporter, I have not used them yet
As for question 3, push down on the D-pad and push right to the camera mode. You should be able to press A. Sometimes there is a huge lag time between the press and the snap of the pic. I have many issues with the controller button. It may need to be reported.
I would also like to point out that when given help it is common courtesy to leave a ‘like’ so people will know you have read the post and appreciated the help. That would be the little heart shaped icon at the bottom of each post , in case you do not know where it is.
