i have two questions, is this an old GPS II ?? then i google on PoweBox-Systems GPS II i get some search results that it is. but also another one that looks more modern.
and my second question, can this be used with my new iGyro 3xtra (silver colored Gyro) to have man gain be set to speed??
i bought the GPS used, so if it doesn't work i dident lost that much money.
