Radio is fine but won't play all dvds

I'm only semi-tech saavy and mainly bought this unit based on the positive reviews and because it looked very similar to the worn out unit that came with our trailer. I had to modify the opening in the cabinet a bit to get it installed it is slightly larger the the old worn out one. Fits good, sounds great and to my utter amazement it plays DVD's ( I guess I missed that part in the decription). Anyway it was just what the doctor ordered I am very pleased with this purchase. My wife and I are retired and expect to enjoy this system while we cruise around the country.

This came stock in my travel trailer. It only lasted 2-years before dying!! I have seen many complaints from other owners of Forest River travel trailers that had this same system. Do not buy!

Very disappointed. Installed in RV as a replacement to upgrade sound quality. While sound improvement has been very good, unfortunately DVD player is not reading majority of DVDs that old system did play successfully. Already cleaned DVDs and tried in other devices and DVDs performed successfully in those devices. The screen occasionally shows, "This Player is incompatible with this region marking of this disc", when trying these DVDs. And this seems to be intermittent as it immediately reads and plays some DVDs that are from the same producer and manufacturer. Unfortunately if this unit is operating as designed, it is a wasted purchase, and may not be resolved by a replacement.
UPDATE: After a very prompt response from QAV Division of Patrick Industries verifying the unit is defective and advising me to return it, I've completed the initial return steps and process to Amazon and will be receiving a new one. Very impressive response from both the supplier and Amazon. I've changed the stars accordingly and will update them again after receiving and successful operation of new unit.

Additionally, as new as this unit is, why it's not designed to play Blu Ray, is also hard to understand.

After receiving replacement unit, I'm very satisfied with it's operation and quality of video and sound in our RV. Very thankful for supplier and amazon quick resolution in the receipt and return process to obtain replacement unit. Installation was easy and operation procedures simple to use. We installed additional Blu Ray player to handle Blu Ray discs and with that running the TV sound through the iRV34 provides good quality sound during the use of that player.

Do not buy this product. Used it once and it would not eject the dvd
