dvd/nav unit for 08 cobalt ls

Hello, I'd like to hear some suggestions on dvd/nav units for this car. My son is looking to make the purchase and knows that it pays to do your homework. He wants a HU that has only one slot, has bluetooth, I-Pod compatable, and up-gradeable in the nav dept. He already has 2 amps, a sub, and decent aftermarket speakers. He is still using the stock GM AM/FM/CD/Satellite HU. We would like to hear of some suggestions for a brand and model that would fit his criteria. Thanks."That'll get ya 10 in Leavenworth,11 in Twelveworth, or 5 & 10 in Woolworth". Groucho Marx                                                      

Clarion or Kenwood are my choices.Jeff

Thanks Jeff. My son has had his eye on the Clarion NZ409. It seemed to have all the features he wanted. Thanks again for your reply, it means alot to have someone in the business to give an honest opinion."That'll get ya 10 in Leavenworth,11 in Twelveworth, or 5 & 10 in Woolworth".

I like the looks of the NX509 better. Price is more but I like the clean lines of the 509 better.Jeff
