My uvo system died a month ago. The local Kia dealership was useless. I've been through all the online searches, forums, dealership, youtube video and friends/family mechanics to no avail. I did figure out that it wasn't the battery killing the radio but the radio killed the battery by continually trying to load the OS. I pulled the media fuse and stopped the drain. Found a LOT of used and refurbished radios on ebay with a wide range of prices and warranties. The question I'm having trouble answering is, does the replacement radio need to be flashed/reflashed to load the OS? The reflash was what I took it to the dealership for and they were useless. I couldn't get a straight answer, then they tried to charge me $140 for nothing and $850 for a refurbished radio. My mechanic son was with me and we walked out and spent the money on a nice steak dinner instead. So, does the newly installed radio come with the OS loaded, auto-upload or need the flash drive OS upload?
