Jensen VM9510 or PA PTID - 900 PKG?

Don't have a lot of knowledge with car audio, but I can get either the Jensen Vm9510 or Power Acoustik's PTID - 900 for an extremely cheap price. Which one would be better? Can these units control changers of any sort? Will they interface with an IPod? Any info would be greatly appreciated, definitely looking for an in dash LCD, always up for suggestions.

dont know about the PA, but the jensen does not do any of that--no cd changer or ipod.  the jensen is good for what it is just think that you get what you pay for.  not many adds on, low outputs for amps and only a matter of time before it craps out.  save your monney and get a nice kenwwod, pioneer, panasonic, alpine, or eclipse in dash screen.If you say "I already know how", don't ask me a single question.
