I owned one of these for a year....you will find yourself shouting into your downed visor and additionally leaning forward to make yourself heard when driving on the motorway..not a good safety move....you will need to get used to repeating yourself whilst talking on this unit.It has a very distracting blue flashing light when operating and mine froze in its 'on' state meaning I had to leave the battery to discharge before it reset on start-up (Approx 3 days!)....save up for a while longer and treat yourself to something better..mine went in the bin.
