Ordered a charger for my Garmin 255WT. Should have been skeptical when it was marked V3Blackbery8100. This is NOT a charger for a Garmin product. When plugged in, you get a Green Line and picture of a computer on the charger. Same as I get when I am updating maps. I unfortunately did not try it within the 30 day guarantee period. Bought it because it was supposedly on sale from 24.95 to 15.95, with free shipping. Listed as limited time only! HA HA it's still on sale for the same price. Don't waste your time with this company to save money. You are just throwing it away!
