Use this USB adapter to connect common 5-pin mini USB cables to newer devices using the Micro B connector.
Tried lots of cables and adapters with my Garmin Nüvi having a Micro B connector. This adapter DID seem to work as a data transfer cable. Lots of other cables and adapters did not.
I have been using mine for several months now with out any issues. Unlike some cheap ones, this one DOES transmit data! I use it to charge and sync my Windows phone to the computer. I will be buying several more of these as soon as I place another order. (to justify shipping....)
Buy it, you won't regret it!
Good experience...On time delivery...No hassles!
