A:AnswerThis should help you out. I would go with the 2557lmt just because it gives you the option to Auto Sort Multiple Destinations. So if you have a road trip you can just enter all your data in then hit the road.

A:AnswerGarmin's nuvi 2557LMT includes a built-in rechargeable lithium-ion battery. While battery life will fade over the course of time and normal use, this is normal for all rechargeable batteries. They are also not consumer-replaceable, so you would need to contact Garmin directly or work with a factory-authorized service provider if your nuvi 2557LMT cannot hold a charge.
A:AnswerYes, that vehicle power cable is included with the nuvi 2557LMT. The following accessories are included:
-Lifetime traffic antenna/vehicle power cable
-Vehicle suction cup mount
-USB cable
-Quick start manual
A:AnswerI have the 2557 for almost a year. I have traveled around San Antonio with no problems. I love the magnified interchange view. I have travel from San Antonio to Biloxi, Mi with no problems. That is over 600 miles. I recommend the 2557 with no reservations.
