Can I exchange the NAV SD card? I believe the unit is fine but the SD card is corrupted. I still can't get the back up camera working and I'm not getting any AM radio stations. Their were 2 antenna connections, one white and one blue. I sent in a picture and was advised to disregard the blue one. There was no port to plug it into, please advise, Thanks The unit was purchased through Amazon. Order # 112-0861141-3634656.
On the good side the DVD looks so good that it feels like I'm in a theater. I love the look and feel of the unit and hope to resolve these remaining problems. I'd rather not have to return it to Amazon.
