Maxx car dock issue

[davep471]

Hi. Just got the car dock installed and having an issue. If I am already using navigation and plug it into the dock, the navigation screen turns black and I have to reboot the phone. Also, if I am using navigation while it is plugged into the dock and go and remove it, the same black screen appears. Everything else seems to work except this navigation issue. If I have the phone plugged in and am using navigation I can't remove the phone to answer a call without the navigation locking up and requiring a re-boot. Is anyone else having this issue and/or is there a work around? Basically I have to exit navigation then plug/unplug the phone from the dock and then turn back on navigation and re-enter the address as it does not save. Very cumbersome, please help?
