Seems to be a common issue with the encoder in them. I own 2 of them one older and another about 5 months old and both with the same quirk. Seems to be the nature of the beast and for me although annoying it's livable. Not sure why they don't just use a better control when they're built ...Thing's still in warranty. I already started a return on it. Just gonna have to wait without a radio for a day I suppose. I just don't want the knob breaking on me completely in the future...
Welcome! I have the 5555 and it has a lot of features and is probably the best bang for your buck. I have not seen the 6666 but I think I is a little smaller than the 5555. The 5555 can be put in 11m mode with a few button pushes on the front. There is another thread here, just do a search. I have my 5555 in my truck and like it better than the Galaxy 99v that it replaced.Several threads on this topic, I won't start a new one. Hope to get a reply. Of the two, 5555 or 6666, which is working better for you in a mobile. I'm a trucker running a 980 on the dash mount now and have issues seeing the display in the sun. I like the accessibility of more controls up front on the 5555 vs. Menu, but the 6666 seems to pack in a little more (power and filter). Display issues aside, they both sound to be a step up from the 980.
Another question, do they come ready to run 11 meters out of the box?
I run the 6666 mobile.. The 6666 is one of the best mobiles I've ever had.
