I was given an older GPS unit (1991 is the only date I could find in the owners manual). It is a Sony PYXIS IPS-360. It has everything that it came with including the case and owners manuals, looks like it has never been used actually. Anyway, my question is, what do you reckon it is worth? I have searched to no avail. It is in mint condition with all its components. It is RX only does not TX, another ham gave it to me because he couldnt use it for APRS, kinda neat, dont plan on sellin it, but I figure Ill set it up in the car just for the heck of it, anyway, can anyone point me in the direction as to what its worth just for kicks?
