Yes, basically a little pop-up window appears on the right of the map with the turn directions, road name etc., together withe the distance to the turn, counting down (visibly and verbaly) until you actually reach the turn. It also gives you an approximate time to when you will reach the turn based on current progress etc.
I've only had my 2610 a month or so and only used it on the bike on Monday this week. On the bike it is fantastic, I used it without the sound as my headphone adapter (2.5mm to 3.5mm) has not yet arrived.
I work near Heathrow and live in East Surrey so I normally travel 44m arount the M25. I set the 2610 to take me home avoiding highways, in the shortest possible distance. Off I went and it was perfect, I used roads I have never been on before and the directions were timely and totally accurate, even to the point where you need to keep left or right for upcoming turns or feeds.
Go off route and it recalculates in seconds to keep you on track.
It got me home slower than the motorway, fair enough, but in 29miles instead of 44.
The only thing I had a problem with was the touch screen when wearing gloves. the main screen area was OK but the corners and edges were not always responsive.
I cannot recommend a GPSR enough, you won't be dissapointed.
But for which model? That you must decide yourself.
