We have a 2015 Landmark Key Largo. The media player in the outside entertainment center is a Furrion FUR DV 5100 and it has quit working. We can not find a replacement unit on the internet (where does Heartland get these odd brands?) We're also having a problem finding another brand that will fit into the space available. We have a call into Furrion but so far no response. Has anyone else experienced this and do you have a resolution. It appears that the face plate has quit as the lights for the CD.DVD still light up.
