I have a dash mounting kit that I used to use with my 180 back in the day. It is magnetic, and a little oval shaped adhesive backed metal disc on the back of the phone holds the phone in place. I'm thinking about using it with my 600, but I noticed that when I get the phone near the magnet there is magnetic attraction without the disc even being on the phone. Should I worry about using this device? It never seemed to hurt my 180 - just normal use was enough to damage that flimsy piece of crap...
