Not a problem at all wait till you hit my age and ask a question lol
As mentioned there are tons of aftermarket radios that will do the trick,, Depends on your budget, But the more you spend on a unit the better the picture and sound from the radio ! I also learned you get what you pay for ,A better unit will usually hold up better then a cheapo. If you travel a lot the GARMIN GPS/Back up camera is a good option and is a good brand. They also have a refurb section to save a few bucks, I have a Old Garmin Refurb GPS that is 10+ years old FYI
