One of the reasons I ride a bike is to get away from stuff like phone calls; have no interest in speaking to anyone when I am on it so no idea whether or how can connect phone to the 390 I am afraid.
I've just bought a 2nd hand 660, prior to that I had a Quest and 2610.
it all works fine but feck me that screen is shit. Anything brighter than an overcast day and you can barely see it. Get the sun behind you and you're fecked.
Are all the 'modern' GPS's like that or is it just the 660?
