Both to be sold together. I have the box and manual (shown). I have used these but no longer have any interest in using them as we have hybrid cars. They were designed to be compatible with some of the Nuvi range of GPS devices, however I did connect them to an app on my Android phone.

They connect to the OBD II connector on the car and will relay that information wirelessly to whatever device/app you can connect to it. Suggest you research on the Garmin website if unsure what they are capable of.

Will post at buyers cost. Could pickup in Rangiora or handover at my work at airport 8am-3pm week days.
