Dual XGPS300 GPS Navigation & Battery Cradle for iPod Touch

Pros: adds a GPS function to Ipod Touch; the cradle speaker is loud enough to hear the navigation instruction. Note that it does not have a microphone.

Cons: Local streets are not labeled.

Summary: Can you imagine a map that does not label local streets? This map labels only major highways and major roads. you won't be able to tell the approaching street from the map until the cradle announce it. The speaking voice is robotic. At times it uses uncommon street name and you really wish the street is labeled.
The GPS signal is not consistent. Sometime can't detect any signal. cradle is chunky, not matching Touch's sleek design. It is difficult to get Touch out of cradle. If you use GPS function, the cradle won't charge Touch. And Touch's battery gets used up very quickly in the GPS mode.
