Hi everyone, my wife and I have just purchased a 2018 Bailey unicorn valencia, my wife is hard of hearing and wears hearing aids. We have been away in this van for four weeks in Scotland returning home next week. The problem is when my wife enters the van she gets a funny noise through her aids this goes away when she leaves the van this makes it very hard for her to watch TV . This did not happen during the first few days but now it is constant when she is in the van. I am thinking tracker, and we have no plans to use this device but we need to find the problem so it could be removed to se
