It's always worked great. It's been running my Broadcastify feed since I purchased it in Aug. 2021. There's no hum or buzz. All original accessories including the auto install kit, antenna, power supply, box, packing, manuals and shipping box are included. I never took the plastic screen protector off. No upgrades have been added. I'll erase the programming unless you tell me not to. I'll ship it Priority Mail, insured to the lower 48 at no charge to you. Contact me for pricing to AK or HI PayPal works best for me but I'm flexible. Absolutely no return if the serial # is removed or tampered with. Thanks for looking!
