Title: will not work for map upgrades
Product review: Reading the other reviews on here suggested that it would work for upgrading my map on my GPS device, a Nuvi 2450. I contacted Garmin customer service and they couldn't figure it out. I ended up deleting all my contacts and restoring the factory setting, and finally a technician mentioned that the data cable should be a MICTRO cable and plug directly into the GPS unit, not into the cradle. So I bought yet another cable, but this time it was the right one and then the upgrade went through. So this was a waste of money for me.
Would you say this review depicts the product in a flattering or unflattering light?
