Question: Fast shipment and easy to install. I don’t have any mechanic experience and even have my friend install the back off camera for my car last year. My friend is out of town for his business trip and I have to install it by myself and I did it just in 30 minutes!!! It worth my dollars and quality is good over my expectation. I am still exploring all the features of this new car radio (sorry I am not a very high tech person) but so far it meets all my needs and functioned very well for me. Quick and easy to connect with my smartphone.

Answer: positive
