Thinking about a new GPS (although I have yet to seek budget approval 
        

 )
         
        
 The Zumo 220 looks to be a reasonable buy � a lot cheaper than the 660.
         
        
 The only disadvantage is slightly smaller screen, lack of MP3 player and headphone socket (as far as I can see).
         
        
 I downloaded and read the user manual and it seems to do everything.
         
        
 Hard to tell if the bike mount is "secure" from the pictures on the web (I once lost a Quest on the M4 
        

 )
         
        
 And why is the old Zumo 550 still so expensive ?
