Review
I had spent a lot of time researching the Pioneer AVG-VDP1 before taking the plunge on something that wasn't all that familiar to me. I must say after having it installed and integrated with my factory sound system, that this sound processor it truly a work of art. Now, you can surely scrap your current system and spent thousands on all brand new equipment, but likely the AVG-VDP1 will help you avoid that and give you the crisp, clear, vibrant sound you're looking for in a car audio system. It has tremendous capabilities to enhance my car's sound, with tuning for the specific cabin space and easy to use controls to customize the sound without needing a degree in car audiosonics. All I have to say is, for a few hundred bucks and a few more for a professional installation, the AVG-VDP1 revamped my car's audio system and I feel confident to expand and add other components now to it. I am truly impressed with this product!

What I like
Provided me with the power to customize the tones of my sound system! Awesome!

What I do not like
Expensive price.

Review
This little Pioneer product displays all sorts of car data (i.e. estimated horsepower, acceleration etc. in addition to the usual RPM and speed) without cluttering my dash, and I like how I can change the display interface between several different display interfaces. Best yet, I can even customize it to my very own display scheme! Easy to use too.

What I like
Displays lots of car info in one place. Easy to use. Different interesting looking interfaces to choose from.

What I do not like
