Good Morning

My husband and I are picking up our new 2021 Transcend Xplor on Wednesday! It's the biggest TT we've owned. It is pre-wired for a back up camera. It is my understanding that GD has wired it to be a plug and play add-on.

I was thinking of getting one for my husband (or for our marriage to reduce stress and disagreements during parking) for his birthday. I was wondering people's thoughts on the back up cameras.
Is it worth it?
Is there a suggested brand?
What is the typical cost?
Is it indeed plug and play?

Thank you!
