Hi guys,
Thanks for all the PM. I'll add more info here from the questions asked. This set is "brand new". It's a USA set from Amazon, its open as I charged it but never use as it laid dormant while I was busy these 2 months but I decided to go with another solution.
Warranty wise, its USA, Garmin Singapore can cover cost of sending only. That said, I've quite a few Garmin GPS and none has ever failed. I can provide a 1 week personal warranty for this. Also, note I'm selling it quite cheap compared to sets here in SG unless you're refering to export sets prices in which case, the warranty issue will be same as this set.
Note this is a Montana 650. Its one of the top offering from Garmin. It usually does not come with any maps preloaded. However, I can help you load in either Malsing or Malfree map. It works just like any of the other Garmin Nuvi GPS
