Hacking the 730n OS
 
I've been playing around with the RHR 2.136.ISO file that *sox* provided (thank you *sox*) to see if there's a way to modify the sound files and/or OS graphics.

I found the uconnect voice files. Seem like it would be easy enough to modify them. For example, the "Phone Call Completed BeeBoop" that plays when a call ends is just a .WAV file. I'm thinking it would be easy enough to record a new .WAV file and substitute it. So long as the file name is the same, it "should" work.

I'm guessing the graphics are the .ANS files but I can't seem to get them open.

From the little research I've done, it sounds like the OS is qnx based and I don't know sh!t about qnx. Anyone know how the OS was compiled (if it was compiled) or how to uncompile it for viewing? I really want to get into the OS graphics files, which I'm guessing are in the ISO.

Also, before I brick my 730n, anyone been down this road before and have some input?

I'm not a software engineer but I am an engineer so it's in my nature to take things apart...:D

Greetings,

Being a construction project manager, I understand what you are going thru.

With regards, to QNX, it was developed by a subsidiary company of Harman who sold to Blackberry.

Check out this link for your research:

Best for now.:)

Re: Hacking the 730n OS
 
Back when I had my 08 Limited Grand Cherokee with the 730N RER I played around with it. I took the hard drive out and cloned the disk image to a different disk. I then installed a QNX x86 build(they had a developers version for free download at the time, no idea if they still do) in a VM and mounted the cloned OS disk to the VM and looked around.

I was hoping to use a bigger HD and resize partitions to have more space for MP3s. Although I was able to do it, and via the OS it showed all the extra space, when I placed it back in the unit, it only used the original total space. Guessing their was some hard coded software limit.

It's been so long now, I don't remember much, but you can probably do the same if you have some familiarity with Linux. I didn't look at changing picture or audio files at the time.

I had posted a bunch of information at the http://mofv.com/mygig site, which was the main site on the internet supplying MyGig info and updates, but it seems to be down now.

I have some reading to do. Thanks for the link.

Mofv has been down for at least a few weeks! Sort of sucks as just about every search I do leads back to that site :mad:

Greetings,

2 years ago, I saw a company on eBay that sells Uconnect radios. Part of their upgrade package included some software modifications and a link to the website. I would try searching on eBay first find out the sellers and check their offers. If you can find them, maybe the can lead you in the right direction.

I never followed up on this because I change to an aftermarket radio for the better audio quality.

Best for now.:)

Thank you for the quick response. I am really not worried about sound quality. My Sonus Faber Conciertos do that for me in my home. :D

I am looking to add an auxiliary screen to control my auxiliary light/accessories via bluetooth.

Greetings,

Great speakers. Nothing beats the European speakers and the raw drivers they use.

Another very long shot is try one of the lockpic sellers and try get some info out of them. Bi-directional bluetooth, RF or IR is vary rare in the 12 volt world. Once you possible find the hack it might be easier to convert one of the home automation device for your requirements. Just to give you an idea:

Xantech.com

Thank you. I will look into it.

I found a programmer that wants to take on the challenge and I will post my progress.
