I purchased this device from the local Radio Shack for a friend. In attempting to update the maps on this device we were forced to contact technical support in an attempt to find the "product key". In the short, but pleasant, discussion with the Mio representative I found out that Mio would no longer be providing updates to the maps for this device. If a GPS provider isn't going to support the maps for its product across the long term, then the device isn't worth the investment. I will avoid Mio products in the future.
