For an 06 Ody with Navi DVD version 4.31:
The file you need to modify is 05Touch2.bin. Not 06Touch2.bin.
The startup screen bitmap file you want to replace is Opening1.bmp. Not back.bmp.
hcvt.exe converts a 480x234x24-bit bitmap to a 16-bit bitmap of the required 224,712 bytes. Available as hcvt.zip from http://stevemg.sc30.info/hcvt/
OK, so I'm attempting this on my own, following the steps on the Acura thread but using the file names you've provided.
I've encountered two problems:
1. hcvt converts the file to a format that dumpnavi will not accept. So I converted it to the specs in the Acura thread 8-bit, 173 colours, etc., but then....
2. ...dumpnavi crashes on my computer when I try to extract the files. This is using both the command line and gui versions.
I think that second problem is going to be a killer for me, unless there is some other version of dumpnavi that will work on my computer. I'm going to keep trying, but I'm not hopeful.
My navi came with two map DVDs. Does it matter which one you get the bin files from?
