    First off I want to say thank you so much, I was about to install the device in my truck this morning in about 30 minutes. The thing that took the longest was getting the little washer on the end of the six cord after I drilled it, super easy setup. Also thank you for knowing the unit well enough to tell me I didn't have the wrong part just needed to install it in a different area. You guys replayed really quick and replied while I was on the night shift (never seen that before!). Thank you again and I will be a customer again.

    Discount Car Stereo not only provided exactly what I needed for my vehicle, the level of customer service was beyond expectations. I reached out via email, concerned that I had purchased the wrong part by mistake. Within a couple of minutes I had gotten an email response back assuring me that I had made the right purchase. Not only did I get an instant response, the email included a link to the directions I needed for the installation. Professional, quick, and thorough. I don’t know what else you could ask for
