I purchased the Z1 about a year ago and the estimated arrival time has always been way off. Does anyone else have this problem? Is there anything I can do to make it more accurate? Also, the bluetooth has the bad echo problem and I understand there is a suposed fix out there but I would lose my "flash the headlights" bypass. Does this bluetooth fix work and is it worth losing the bypass feature? Lastly, over the last couple of months, when the truck has been sitting in the sun, the Z1 freezes on the pioneer screen and will not work unless I restart the truck? Any insight into these issu
