Have You Successfully Fitted A Raspberry Pi To Your Factory Tv/nav System

Has anyone actually hooked up a Raspberry Pi and been happy with the results.


Why I ask, is I have a 2005 stagea M35 with factory Nav/TV etc and connected my Raspberry Pi via the aux input at the factory TV tuner box in the rear left quarter.


I have tried two different ways to connect the Raspberry Pi, one via the analogue video output using RCA cable and 3.5 phone jack for sound out connected directly to the aux ( VTR ) input.


This gave me a good sound, but picture quality on the factory screen was fairly poor.


The other method was using HDMI output from the Raspberry Pi then via a HDMI to composite adaptor out to the aux ( VTR ) input again. Results again were much the same, good sound, but picture quality was average.


I'm using XBMC on my Raspberry Pi.


I would like to get this so the picture is of good enough quality that I can easily read the words on the screen without them being a little fussy and very small.


I guessing this may be a case of changing settings in the workings of XBMC maybe, but as of yet I have not managed to be able to change the screen resolution size to see any difference in what I see on the small car screen.


I know if I changed the screen to one that had HDMI input, that I would get a lot better screen picture, but I would think the factory screen would still give reasonable results.


Before anybody suggests taking my car to see who ever, I just wish to point out that I'm in New Zealand.


I'm happy to change any wiring, or direct link something into the factory tv tuner if that is needed.


Any help with this would be much appreciated.

I'm looking at this, but I am hoping to replace the screen with something more modern. the standard screen is 5.5" diagonal, which is an unusual size. Fitting a 4.3" would be easy but a backwards step in size. 7" seems just a bit too big to make it fit.. and there's not really anything in between.

otherwise if you can get a decent result with the factory screen, it's a good size so i'd be happy to leave it. haven't tried pulling mine apart yet. I'm on the lookout for a spare TV unit to try replacing the screen as above.. don't feel like leaving a hole in my dash while I mess around :P

where does the composite video input plug in for the screen?

Geoff,

Screen is a sharp or Panasonic in the m35 from memory.

It needs a data feed to fire it as there are 4 inputs that need to be setup.

The 34 is a 5.8" unit and easier as it is a sharp unit. I have the datasheet for that one and if you can generate RGBS then you are on your way. That unit is a twin input with a logic trigger to select it.

This is a later motorized screen. Similar idea. Toshiba supplied. The board supplies all of the signals to run it.

      Sounds good. Provided the panel is flat/level I'd be happy to start the painting process.  While you are learning, for sure you could do this. Its only paint, you can always sand it all back and start again. Its only your time and money on materials, but while you're learning, really its time and money spent on your education.  Once you know how to do this bodywork and painting, you won't want to waste your time and money on frivolous activities lol.

      Yep I will use a guide coat after putting filler, I will do it on the whole panel as I'm a beginner so chances I've made quite a few errors. In that photo, I think that was a low spot, I just for example said to pretend it's flat but I will put filler + guide coat after to assess where I'm at. Yep with that picture, the panel is wet as it rained when I took the photo. But all those scratches are completely smooth, I went over it with 240 grit and can't feel it, even with my nail digging into it. I was legit thinking to buy a 2k can and spray primer to see how it turns out but then thought to myself it's going to be a mess doing it haha. Good mention there. Thanks for all that info I think I know what to do next.

      Prior to laying down the primer, you need to make sure the surface is completely level. For example, based on this picture, I strongly suspect that the areas marked in blue are higher then the area marked in green.  If you spray primer over this entire area, then paint and clear it, the finished result will 100% show the low area. It will stick out like dogs balls. Unfortunately the paint won't magically level out the low areas as you lay it down.  Without seeing it in person, I expect that the green area will need to be filled, then use a guide coat and check that the entire repair area is level with a large sanding block.  With this picture, are you saying that even though you can see the scratches, the panel is in fact completely smooth and flat? If this is the case sure you could prep and paint it as it is.     The picture with the paint you described as blistering, it's hard for me to comment on from the photo alone. It looks like the panel is wet? Dunno, looks strange. Does the panel feel as smooth as glass when you run your hand over it? **** Going back to your question again, generally you would only sand the primer if you made a mistake while laying down the primer.  If the panel is prepped properly and you lay the primer down properly, you should not need to sand the primer.  This wouldn't work - Don't prep the panel. Spray primer and see how it turns out. Sand the areas where the issues appear. Spray more primer and see how it turns out. Sand the areas....... Yeah you'd go round and round in circles getting no where.
