I don't have the model numbers handy, but my trailer originally came with a Jensen stereo/CD/DVD player and when it died I replaced it last spring with a new model. Same as yours I think. The connectors for both the power and speakers were identical and they were wired the same so it was as simple as unplugging the old one and plugging in the new one.
