one of the primary reason I buy a Garmin 1450 LMT be the offer of lifetime map update as I have have problem in the past with out of date gp system . now I be leave on a trip and it be time to perform a update but the unit seem incapable of do so . the update software see my gp attach via usb and recognize the model and serial number but when I tell it to update , it fail say that there be not enough room on the device , delete unnecessary file . the problem be that I have not add any file ! I recognize that over time Garmin 's map get larger and there be a finite amount of memory on the unit but this unit be only a few month old . how can Garmin market a unit as have lifetime update and then have it run out of room in a few month ? this seem extremely irresponsible of the company and they should offer a replacement unit that be capable of receive map for some time into the future . I have use several Garmin product in the past and be happy but I be very disappoint in this one and in Garmin 's approach to marketing seemingly inadequate unit . I will gladly rewrite this in a positive note if Garmin agree to fix the problem and turn this around because otherwise I be happy with the device .
