I don't think they did.They said it was stock antenna wire was broken.They wanted me to pay $50.00 more for a stock antenna.I told them I just received new cartel and I will bring it to them.I did they put it in and same thing.They wanted another $50.00 to try to flash the firmware and reinstall it.But no guarantee..Think they weren't qualified and I wasn't gonna take a chance.I can move camera..I have ipad 2 mini it doesn't have sub port only mini.So I can't try the firmware thing.It says. All up to date.everything is calibrated..
