If you have either an IRV33 or IRV66 radio then you can definitely go direct to Todd. He is a direct contact at Patrick Industries (the radio manufacturer) and all of the models (new designs) that were installed up until about a month ago are suspect. Todd only requires the model number, a brief description of the problem and your shipping address. He will ask for a credit card to guarantee that you will box up the faulty radio and send it back, but the new radio comes with a prepaid trip back.
I got my new radio within three days and it now works properly.
