I have been putting this unit through its paces and it appears to be doing a good job. I am a litte disappointed that to use all of the features that there is an additional small charge. But with out paying for all the features, it is doing what I had hope it would. It is the right size for my car, and it came new in its packaging. It looks good and if it continues doing a good job, I am thinking of getting one for my wife's car.
