HOW TO: DIY VIM unlock, enable Reverse Cam for v9, and other radio tweaks

[HoLLo]

I was able to figure out how to flash VIM unlock, and enable Reverse Cam option for V9 radios, the two difficult radio tweaks that everyone keeps secret. Big thanks to my friend Nic Powell that helped contribute data and bin files for me to flash my radio countless times and figure this out. Please share this with anyone who wants this information, I did it for the car modding community, not for profit.

As always, you perform these mods at your own risk, I am not responsible for any possible damages you cause to your car. Read it thoroughly before attempting anything.

There are plenty of vendors who sell boxes that plug into your OBD2 port that can also perform these tweaks, so if you are unsure about removing your radio and programming an EEPROM, you have options to reach out to online vendors, but now you have a real DIY choice. Enjoy.

Do not download the file, just bookmark it since I will be evolving it as I add more information to the guide.

EDIT: I've had many questions about this. Version 9 is ONLY needed for the factory Reverse Camera feature. All other mods can be performance on ANY version radio.

Thanks for this info. Is OFFSET 00E (00 to 55) on EEPROM 'spreadsheet"? I believe OFFSET 635 is on VIM 'spreadsheet'..6across, 15 down.These two things are not as clearly shown as other change settings. Great work, I haven't checked my radio yet to see if it is V9. I hope you see this, my posts usually make the thread disappear from Today's Posts.

If you click on an offset, the hex editor software will show you the offset that is in the bottom right corner. It will be like 8 digits, the last 3 digits are what you're looking for.

I mostly used HxD hex editor software when I was experimenting, you can make modifications to the files, save them, and open in the programmer software and it made it easier.

Thanks for the reply. If my radio is compatable. I will use this guide and install back-up camera. The auto-reverse switch feature has been thr Holy Grail of VIM unlock.

I looked over your instructions again. This seems do-able. Hopefully I will be able to find a reverse camera with out the lines to use as stated in your instructions.

I'm just waiting for my rear aux cable to get to me then I'm going to try this out. I already received all the parts from the DIY.

This worked well. I was able change everything around on my radio. I did change the color to blue but I think I'm going back to red as it doesn't look appealing with the red buttons. I do have a V9 radio but I want to note the reverse camera enable was not at 635 on mine. It was at 633.

How did you figure this out?

Edit...

I was wrong. The reverse enable was at 635 just like the instructions stated. The only deviation was that mine from the factory was set to 00 and not 02 like the instructions states.

Changing 633 to 01 enables a menu option called "HMS Messages"... whatever that is I dont know.

I've attached my BIN's to compare.

That is for the Holden Massage System. It was usually fitted to very upmarket Luminas for the middle east. It allows you to communicate messages through the radio to tell the massaging seats what to do. If you can figure out the happy endings code I am sure there will be much interest from that region on that. Unfortunately the US G8s do not come with the proper seats for any of it to work.
