I have same problem. Only upgraded my V6 to 360 a week or so ago and have spoken to various VM departments.
All have said it is a third party device problem not VM’s.
Last advisor seemed to understand the issue and promised to elevate the problem to the appropriate department. Not holding my breath.
i have a Yamaha YSP-2700 which pairs perfectly for an hour or sometimes a whole day. It then decides to change it to a Pioneer and then the remote stops working. No problems with the V6 box so definitely a software problem.
