I have left other comments on other reviews that did not give this unit the respect it deserves. I have found very few tweaks that I would have in the design. Being able to change color output. It may exist I just have not found it. This unit does more than any unit I have ever used. A larger remote would also be idea. Not every one is young that enjoys quality sound while cruising.What I recommend: Don’t let installers use a wire harness that needs to be cut or spliced or remove your factory wiring harness. This unit can be easily installed by your self if you know how to remove your old unit, it needs keys and may be security bolted and hard to reach. That is a security feature. If you can not do that. Take it to a professional installer. Before you do, I recommend you find a plug and play wiring harness for your vehicle. I was able to find one in Sweden on eBay. This eliminates splicing that is usually the problem associated with sound failure. I searched companies like fry’s, radio shack and other audio stores to no avail. Sweden no problem. I found a direct plug and play harness that made the installation easy for my 1992 Ford F250 and I know I will not have a sound problem at the receiver.I have not changed my factory speakers. They are 21 years old and work well. I am going to replace them because they can not fully utilize the power put out by this system. I can turn up the sound half way and my speakers are maxed out. They are 150 watts.The video output is awesome. It is a small screen but for my purpose works very well.I give this unit 5 stars. It takes a beating in my Ford F250 4×4. It is heavy duty with an leaf springs front and back. If it can take this abuse your city road hugger will not have a problem.
