A:AnswerNo, it does not come with a back up camera but it does come with the capability built in. You have to purchase a camera separately. I purchased the Bestbuy back up camera & it works great!
Yes, you can play CDs & DVDs on it.
I am not sure about connecting a CD Changer. I assume so. No one that I know uses the capability anymore since you are able any and all music digitally now.
Yes, it does have GPS capability but with Apple or Android Play it does not need it. GPS comes free with the new phones.
I hope this helps & I am old school in age as well but my kids keep me up to date.
A:AnswerI called the store and the salesman helped me find the right unit for my car. I own a 2011 Impala. The store personnel are very helpful in finding the correct unit for the make and model of your vehicle.
A:AnswerI have an 04 Yukon Denali. It’s not worth the money buying the support modules and wires to keep some things. If you have an iPhone want navigation. Just plug usb. Use the apple car play. If you have android. Buy an iPhone.
