Hi All,
I am looking to integrate bluetooth compatibility for media (Spotify) and calling (Android) control, while retaining the OEM equipment, Head unit and steering controls.
Ideally I would be able to use the existing head unit to display the media, song details, person calling, etc.
I am not a programmer, although have friends who are, and want to see if you all think it is possible to use the PiMOST for this kind of configuration?
Cheers
It should be compatible with a disco 3 however it is untested.
I do have a friend who has one that is interested in the final solution so I can report back once it has been implemented on there
Thanks Mate,
Let me know how you go.
I really like the idea of the project and it’d be great if it is a smooth switch from freelander to D3.
Cheers
Greetings dudes and dudets?
As a fella owns a 20 year ol Discovery 3, as we discovery 3 owner does these days. 
The satnav screen is old, the ihu (head unit) is tired and we dont use cd anymore and fm/am is dead here in Norway, its Dab+ all they way here, I would like to replace the headunit, as we all wish for a such present under the carpet? no… under the christmanst tree. Now yankin out the nav display i can no longer see the 4x4 info screen, and thats handy to have… Yankin out the radio you can not set clock in dash and few other things. I have been lookin or takin a peek on how to take a raspi a canhat and a screen, and connect the hat to the Highspeed can to get engine “vitals” Oil temp,water temp, etc…
I know that the info displayed in the 4x4info screen comes over the highspeed 500kbs bus to the ihu and then over to the most bus and it ends up on the display.
What I would like is to replace the ol screen with a more modern one, to get engine data, gearbox data, transferbox data and read difflock data. and perhaps yank out the ihu and replace it with an aftermarket one but still use the oem amp with speakers… I have tried to sniff the canbus with a j2534 cable and a program called Savvycan that powerfulukltd did a quick video on. But I did not get far at all. I’m not skilled enough for coding or programing. But i do love to tinker with doodabs and whatnots…
So I’ll keep bookmarking this page and have a keen eye on development… Intresting project that I can stand behind and give you a thumbs up or 3 if i have one spare somewhere 
Anywhos, I’m not scared to tear stuff apart in the car… Been there done that so to speak. Dashboard out due to heatermatix leak… And while i was at it, I lifted the chassis from the frame and sendt it to sandbalsting and re paint and undercoating… Its brand new under there now, better than factory…
Upgraded the audio from high line to premium pack. New amp and a few more speakers added…
So If you think this will be doable for an ol Landy and an eager owner to test, blow some fuses say some unholy words, I’d like to support you in this community work 
Hi @Parrafin23
Great to have a fellow LR guy! I’ve always wanted an Disco 3, so I may well be joining you soon. I think it will work on a Disco 3, what I have found from working on the Freelander 2, and then the XF is that so far everything is incredibly similar. The XF is just the same as the FL2 but just with more, so I suspect the FL2 will be very similar to the D3, just with some more features. CAN is a problem between them all as the Can IDs vary so wildly, however the data behind is incredibly similar. The MOST system on the other hand is almost a copy paste!
Hey everyone, I’m new here, but I’m also deeply interested in this effort. My LR3 NEEDS something better.
I actually love the head unit and really just want to build something that ties into it by tapping into the MOST network. I am a software developer, so looking to build something moving forward.
Hi! Does your disco have the OEM touchscreen? I believe it’s similar to the Freelander 2 in that it only does navigation?
The usb board will have good functionality for this, it acts as a usb soundcard and force switches the amplifier to it. However there are a few gotchas with it. After its force switched if you then go to another source it won’t force switch again until MOST network off and on cycle. Running it with a host communicating using the drivers you can run the force switch at will.
The Saab 9-3 thread contains some information on a truly integrated way to do which I’ve done in my Jag XF
Yes, mine does have the touchscreen and yes, it only does navigation and 4x4 information. There’s some secret menus in there that give a fair amount of info…but don’t enable anything. I suppose it’s just displaying canbus data…
Regardless, I do have some questions (will put into a different thread because they are not Disco3 specific).
Right now, focusing on yocto and getting a barebones distro that boots straight into kiosk mode going. Hoping to reduce boot times to under 6 seconds.
