I be envious of all the positive review and wish that I could be write one myself , but there be some serious issue that I have not yet be able to resolve , despite extensive online research . 1 . mountain goat mode - be my own term for the 1350t 's navigational preference . for some unknown reason , it direct I away from main road and highway and towards back road , alley , and most recently , hillside trail that I would consider neither safe nor navigable . I have find many forum post on this issue and have try experiment with both the Avoidance and Shortest\/Fastest setting , but have yet to solve this problem . 2 . City navigation make I feel like I be the object of a Punk would style prank . the slow response time , tendency of the screen to freeze and poor accuracy make it easy to drive right past you turn and trigger the all too familiar `` recalculate '' . I can not tell you how frustrating this can be . even when you do make the recommend turn , you often trigger the `` recalculate '' response . 3 . battery life be average 10-15min on a full charge , which I feel be inadequate . if anyone have any suggestion , please post they in a response . in the meantime , I be go to try a Tom-Tom .
