Hello all,
Great thread! It's been a valuable source of information for me, being that I'm in the USA and purchased the Witson D720V/AVC-9000 on ebay. With the help of this thread I've been able to get IGO 8.3 with the latest US maps and Dimka skin working, as well as the latest WolfNCU desktop running with various skins. Overall I'm quite happy.
Hopefully I'll be able to contribute back to this thread's usefulness... I have two files sent to me from "Bob" at Witson that other's may also find handy.
Once my unit arrived and I'd installed it, I was testing out all the functions and getting familiar with the unit's operation. To my horror, I found that on the GPS OS side of things, there wasn't a VW logo but instead a huge "NISSAN" logo :smile:
I emailed Bob at Witson, who responded the next day. He sent a firmware update and said it would fix the Nissan logo. I believe something was lost in translation as it seems he was under the impression I had a Nissan logo displaying on the iPod/DVD/Radio side of the operating system. His firmware update flashed fine, but did not address the Nissan logo on the GPS function.
I replied back to him with a screen shot and he immediately knew what I was trying to accomplish. He sent a sysupdater.exe file to me along with text instructions, a new .bmp file and even an .mp4 video that showed how to update the logo. He also mentioned that he actually had another system update but warned against using it unless there were major problems with the unit -- I wasn't able to gather if he meant he had another executable that could be run or if he had a newer firmware. I've responded to him and I'm awaiting his reply. I'll post an update when I hear back from him.
Both the firmware update and the sysupdater.exe are available at rapidshare:

Bob's .bmp logo replacement was a simple blue background with white text, and while it admittedly was better than a Nissan graphic, I decided to do some experimenting on my own. I found that the restrictions for getting a properly displayed bitmap require that the image be 400x234 and saved as a 16bit image (higher color resolution can be uploaded but won't be displayed correctly).
I believe it was OzDJ that posted som R32 backgrounds a while ago, so I grabbed one, cropped it down and saved it as 16bit color (it's included in the rar file). It's currently my D720V's GPS splash screen, though I'll soon change this as I own a Jetta TDI :smile:
My hopes are that somebody more knowledgeable than I will be able to make better use of the sysupdater.exe than simply changing logos. If you download and run it, you'll see that there are what appears to be several other options available. Some of these include "OS" and "Boot" -- my assumption being that these options can be updated in a similar manner to the logos. Earlier in this thread there was interest in doing some firmware/resource hacking on our units, I'm thinking this tool could come in handy for that.
Ok, so... I do have a couple of questions regarding these units:
1) When I turn on the unit I see a blue screen for 1-2 seconds until it switches to either iPod or Radio mode. Is this normal, or should I be seeing a VW boot splash?
2) Where can I purchase a backup camera? Mine did not come with a camera or TV antenna. In the USA, OTA TV signals will be replaced with HD signals in February 2009 so I really don't care about TV and wouldn't watch it in the car anyhow. I would like to get a backup camera installed though.
3) Has AM radio reception been resolved with a dual fakra to ISO adapter? I read earlier about the Active Phantom Antenna, but wasn't able to pin down reports on whether or not this would solve our issue. I would like to get both FM and AM reception working.
Thanks!
