No. You can't play .iso files in any standalone DVD player.

Just wanted to add my 2 cents for those who might be having the issue of no video but hear audio. I was having the same problem. I had completed the bypass hack with a single throw/single pole (SPST) toggle switch. I could bypass the warning message and hit the OK button but no video. I did hear audio. I searched everywhere but solution 4 worked for me. The thing for me was that next to the black wire on the harness wasn't empty. It had a purple/white wire with some sort of filter (labeled backup camera hook to reverse gear). I tied into this wire before the filter with another wire (I chose a black wire b/c I was grounding it) and grounded it with the black wire (ground) on the harness. I now have video! Maybe the 4 pole relay hack would have worked better but I had only done the toggle switch hack. I hope this helps others and most importantly thank you Salhi.

Press and HOLD MUTE. If you do install a camera, make sure it supports reversed image output, otherwise your images will appear backwards...

there is a reset button on the left of the cd player. u will need a needle to hit the button. once u hit it, the screen will still say caution but when you touch the screen it will go back to your regular settings

Mine does the same thing, its not a wiring issue as I put a different Pioneer Head Unit in its place and the problem went away. I put it back and the problem returned

I removed my Pioneeer AVH-P4000DVD from my Tacoma pickup to upgrade to an AVH-X2500BT and installed the AVH-P4000DVD in my mustang cobra and found myself suffering from a strange issue (that seems to have happened to a lot of you too). All of a sudden I had lost my audio on my USB and AUX inputs. I tore the net apart for a solution, pouted, drank, and started doing more and more research, and check instruction manuals. I eventually found the solution based of one lone comment someone had mentioned regarding ground and comparing the wiring diagrams for the two decks. I pulled the pioneer harness out of truck and compared it to the pioneer harness in my car and found an inconsistency. This may solve the issue that plagues you as well. Check the harness you are using. I was not able to find a pinout, but the 4 wires on one end of the harness for the AVH-P4000DVD should be +12V battery, +12V ignition, ground, and ground, (yellow, red, black, and black). If you have received the harness for a newer model of pioneer AVH it will still fit fine but one wire is out of place. The second ground wire you need has been replaced by a purple reverse gear sensor for the backup camera. Ground out the purple wire and it should solve your issue... It did for me. Good luck.

better check on your dc wiring system make sure u have fixed them tightly

CONNECT A SWITHC TO THE PARKING BRAKE WIRE ONE OF THE PINS FROM THE SWITCH TO GROUND AND THE OTHER SIDE TO THE PARKING BRAKE WIRE.

This what you do. Connect the video wire to a power suppy and install a switch in the power wire. When you put the DVD in and the warning comes up, turn the switch on then off. This will allow you to watch the DVD without the park brake being applied.
