I'm not familiar with the holux antenna's, but it doesn't seem right that you have to wait for 20 mins to start it up!! I guess this is a common thing with some people.. Anyways, if you can't find the antenna, maybe it's set to the wrong com port in the computer? I don't know what software you're using, but when I search my com ports in streets and trips it finds it everytime. Maybe you're just comming out of hibernation if you're using it on a laptop computer and it is having problems that way.. but I don't know, 20 mins to boot it up seems kinda crazy?? Maybe it's just a faulty mouse? my bu-353 takes about 3 seconds to boot up,,, maybe check into that mouse?
