Either get this
http://www.cyclegadgets.com/products....asp?Item=HARD or you can fashion a bluetooth dongle & adapter, or use a hardwired set of earphones. You cannot hear it at highway speed otherwise, & to look at it would be distracting.
It literally has saved my license...
BTW, NYS has a handfull of fees they tack on when you get a ticket...expect them to increase & for other states to follow as a "vice tax"...or use fee, or whatever term the "revenue patrol" is called.
BTW, is anybody else pissed that they wave radar guns up & down the highways instead of patrolling residential areas? I could care less what speed someone travels at down the NYS Thruway ( limited access interstate ) or on backroads but I have a BIG issue with jacka$$es speeding in residential/school zones.
