I am beginning to think that this is a more widespread problem that should be looked at by Dension. Clearly I am not the only one experiencing these issues. Tom G. has turned me to Dension to take of rhis issue. In his previous posts, he has determined that my unit needs to be sent back, possibly as a defective unit. X5Sport what did Dension do in regards to your last unit?? Did they reinstall for you, provide you with new/refubished units?
