First off , allow I to provide some context to this review . I buy this to replace a Garmin 660 that be steal -lrb- at least I get the valet company to reimburse I -rrb- . in addition to the 660 , I have also use integrated nav system in a Honda and BMW . they provide I with the comparison reference point . another point of reference be that I use the 2460 in a small convertible , and the roof be down unless it be really rain -lrb- which be rare in S. California -rrb- . what I like : - I be surprise by the voice recognition . you do not need to press a button to activate it ; you give the garmin a activation phrase and it continuously listen for that phrase . this end up be far more useful that I expect when I buy the unit - I think I would never use it , when in fact I always use it . it do struggle with noise if I try to use it at highway speed with the roof and window down . it be acceptable if I have the roof down and the window up at highway speed . -lrb- acceptable : I end up need to repeat myself often , but eventually get what I need without need to take my hand off the steer column -rrb- . since most people will have a better controlled noise environment , this feature most likely will work great for they . - the traffic route be much better than on the old 660 . - the unit detect pattern and provide ETA information , with out turn by turn prompt . this be great for the day when traffic decide to back up on you commute - Lane assist , this be now a must have feature for any future nav system I consider . what I wish they have think of : - allow I to request the ETA information without the turn by turn . often I know where I be go but I want the ETA and the traffic advisory , but do not want the turn by turn . what they really mess up : - I can not voice search for destination along my route -lrb- or at my destination -rrb- . when on a long road trip I occasionally will need to search for a gas station , restaurant , etc. . I do not know why they ditch the search option , but have to sift through all the hit that be behind I or way off the beaten path be unacceptable . especially since I tend to use this feature when I be not familiar with the route and I end up need to pull over to manually set the along route search option . - the screen be almost illegible when I be wear my polarize -lrb- not sure if this be the issue -rrb- sun glass and it be in direct sunlight . -lrb- hint , I always have the roof down and I be in S. California - this be often enough to make I miss the 660 screen -rrb- . I end up turn the screen such that it be point down and away from I , and sometimes just resort to take my glass off when look at it . -lrb- edit : correct comment about search along current route - thanks for the info Preston -rrb-
