Purchased a unit for my 2018 F-150. Had problems with sound due to my failure of following proper installation procedure. Tech support was not only on time but was patient in trying to resolve the problem over The period of a week! They were knowledgeable and extremely helpful in trying to determine the problem. It was only after I sent pics of install did the issue immediately get resolved. My bad! These guys were great, product is over the top and support went as far as conference calls to countries outside the US! Very satisfied with the product and all the support!!!
