Thank you for viewing. I purchased this new and stored it without using it after opening the package. It is a Sony GPS unit GPS-CS1KP. The package has some damage. This product is for adding location information to photos taken. Records shooting locations with GPS. Map software included. Compatible models: Sony digital cameras such as "Cyber-shot". Allows for new ways to enjoy photos combined with maps. *This is a very old product, so I don't know if it will work properly. Please purchase only if you understand this product. There are no missing accessories. I will do my best to ship it the same day, so thank you.
