I have an 2008 Lexus IS 250. The car came equipped with backup camera. I don't think it has the backup sensor alert noise. Is that something I can have installed, or do you think I have it and its just turned off. Please advise

 

welcome to the forum

 

I don't know, but it may not have it because those were the earliest years of back-up cameras (relative to today) and things may have not been that tech advanced yet. But why don't you call the nearby Lexus dealership and ask them for a better answer?
