One day we could watch DVDs on the RER 740N. Now we cannot. Using JSCAN to access the ODB2 it shows the DVD region code to be 1, when looking at the live bus info, the radio thinks its a 3. I've reset the DVD region code to 1 and verify it is saved. But the radio continues to believe its region 3. Any ideas most appreciated.

Sounds like the Radio itself is the problem from what your describing; I have a couple of questions as I'm trying to decipher your post;

What is JSCAN? I've never heard of it up until now;

Secondly, you mentioned looking at the "live bus info" What exactly is that - and how are you viewing it?

Just trying to get a better understanding of what you're doing and how you're actually doing it....than maybe I can try to help. I'm not as fluent in some of the more technical terminology as I'd like to be. When you start talking about the CANBUS and live bus info, I start getting a little foggy.

Thanks for taking the time. JSCAN is an app (iPhone in my case) that uses ODB2 port for configuring, see JScan ? OBD JScan ? Mobile Jeep Diagnostic Tool for the sw, see the images at the bottom of that page. It's like a mini-StarScan tool if you will. I used it to turn on the backup camera, day time running lights, and enable my fog lights. $17 per VIN vs $100-200 per dealer visit. JSCAN let's you monitor the CAN bus in real time. So I used it to see what radio (RER) is configured for (DVD region 3) and how the main module is configured. In my case, the XK thinks it's zone 1, and the radio thinks it zone 3. JSCAN has saved me hundreds. Lots of off roaders use it to config for larger tires, gear teeth, etc. Hope that helps, and sorry I was unclear.

I understand now; I don't know what your finances are like - but if you want another option, I'd recommend trying the Appcar-DiagFCA OBD-II software; It's made by Chrysler and it is legitimate professional diagnostic software - a little more expensive then what you are using - $49.00 per VIN but well worth it in my opnion; I've used it and literally gives you complete access to all of your Commanders functions & options. You can read about it in detail here;

Thanks @Big Blue I had seen that and looked into it. Not so much cost of the software but the need to buy a PC and deal with Windows, so I went with JSCAN on my iPhone. At some point I may have to breakdown and buy a PC, learn Windows (sigh) and give it a go...

In the long run, I think it would be a good investment for you; it really is an awesome program.
