Bests & Worsts Reviews from Amazon

I purchased this unit after carefully reviewing its capabilities versus those of competing units. One important feature that led my evaluation was the ability to use maps from other regions. To download a Garmin map into the unit, one must use of a free app called Garmin Express. Unfortunately, as of the writing of this review, Garmin Express does not allow the installation of new regional maps with the Drive 61 or 51 units. I spent several hours trying to make it work (the night before a trip to Europe) and an additional 1.5 hours with tech support (the day of the trip). Tech support was able to reproduce the error with their own test unit and are working on a fix. My interactions with Garmin since have been wonderfully professional, but highly disappointing. It's been too many hours across too many days and I am unwilling to invest more. I will be returning the unit for a refund. Comment to Garmin: My final solution is to use free offline maps from Google on the iPad I already own, even though I was willing to buy a dedicated device from you. So, this particular failure of the QA team at Garmin translates into a loss of a customer, lost revenue and hurts your brand. Why wasn't this tested before releasing the product to consumers?
