There are a couple ways you can approach this. You can go into the store and take a look at the car fi selections they have on display. These should be working samples that you can listen to and check out the features. Then I'd narrow it down to 3 or 4 models and check them out on our website to see what our customers reviews are. I'm a more touch and feel shopper so I need to check them out in person. You may want to ask the Install Bay tech for their suggestions as well. Hope this is of help to you.
