I hate to say this, since there's no nice way to say it, but if you're expecting good results from the Coby system, it probably isn't going to happen
Mine froze up on my first outing and aggravated me to no end. That plus the fact I like to listen to music when I'm not watching TV, and the Coby won't hold a station preset if you change modes or turn it off, I made up my mind to replace it with something better and not worry about trying to get a replacement.
I bought a Samsung home theater system for the house and liked the sound quality, so I went to Circuit City and bought a Samsung system (with 5 speakers plus sub woofer) for the Sundance. I didn't have room in the entertainment center for the 5 disc system like I have at home, so I got the single disc model. Once in a great while it will still freeze up, but I think that is more a disc problem and not the fault of the player, but the sound quality more than makes up for the occasional frreze up.
Since mine is a 3012RE I had plenty of room on top of the entertainment center to mount 3 of the speakers on top of the cabinet, replaced the sub woofer and now I'm looking for a pair of flush ceiling mount speakers to replace the OEM ones.
I might be the only one that feels this way, but I wish Heartland would take the lead and install only the wiring and high end speakers in their units and let the buyers decide which brand of DVD player they want. The heart of any system is ultimately the speakers and a DVD player on it's own is relatively cheap. They could just install a AM/FM/CD player such as they do on the Cyclones and let the buyers decide on which brand of DVD player they want.
