Still looking for a replacement for my NAV ECU and see that the original part 86841-50090 was superceded by 86841-0E010. I'm not sure if that new part number is still gen 4 or is it gen 5. If it's gen 5 will it work with the screen in my 05? I know I'll need angen 5 DVD but I want to ensure compatibility with my screen and resolution. Thanks! Any assistance is appreciated. John
