Just to let people know, I have a d2 for sale. Can't post to the classifieds, as I don't have over 50 posts. I'm legit, located in Orlando, FL for anyone that wants to drop by and check it out.

Everything works on the d2. No cables or anything though, just the unit. The nav dvd is a burned copy, not original. Looking for $320.

The ability to use btb200 and have complete usablity on screen, instead of it showing up as ext. Same thing with HD radio add on unit.

I've noticed there are a few features present in the n4/n5 in the interface not available to the n1-3 versions. A firmware upgrade from Pioneer would fix this, but that is obviously not going to happen. Has anyone tried to put the N4 firmware into a n2 or n3?

I've observed looking at service manuals and the nav dvd's, that the firmware files are numbered differently for every model. Here are my conclusions:

010 files -> 800 900

030 files -> n1?

040 files -> n2-n3, possibly n1?

050 files -> d1-d2

060 files -> z1-z2

070 files -> d3/n4

071 files -> n4, maybe n5

Has anyone tried changing the 071 files to 040 and then force the firmware write to see what happens??

I'll show and example of filenames for n2-3 and the n4.

If renaming the n4 files to n2/n3 names, wonder if it would work?? Has anyone tried this? Does anyone have the boot/bios files? Those aren't on the cd. My n1 and n2 are off for flex cable repair and in my spare time I've been researching to see if this is possible.
