Good thing Amazon shipped your radio because that makes it an easy return.
Also, if you drop off the return at UPS store, the money spent will be refunded by the time you get back home.
That radio had already been converted I would think. I would email Hesenate, and send them the pictures of the radio you got. It could possibly be that Amazon sent you a used radio, and Hesenate did not know about it. I am sure Hesenate does not want a bad review about this mess. Who knows they might make it right.
