Hello,

I have tried to install it on a raspberry pi 3 after installing the latest version of RaspbianOS (Jessie) but I have the issue that it does not properly render the skin.
The board is connected via HDMI to my 1920x1080 tv since I do not have the touchscreen yet.

Does anybody have the same problem?

Thanks?

This question has been answered a 100 times – but once again:

Add
Code:
gpu_mem=256
to /boot/config.txt!

I'm sorry. WAIT no I'm not! I just couldn't scrap the project. It is cheaper to get a new headend unit with all this stuff already to use but well, it just wouldn't be mine!

Let me start with this @jack and chris WELLL DONE!!!!
and all others that have participated and helped.

Open /home/pi/.navit/navit.xml


Sorry jack navit.xml is not located here. At least not on my install.

It is located /etc/navit/navit.xml

sudo nano /etc/navit/navit.xml

For any others that need to change language.

The main menu language location is

/home/pi/.navit/xml/skins/snaga/gui.xml

sudo nano /home/pi/.navit/xml/skins/snaga/gui.xml

It is still in german.
From: Karte Navigation Einstenllungen
To: Map Navigation Settings
Or the language you speak

Here is what I have

RPi3
Current Raspbian (jessie full)
SanDisk Ultra PLUS 32gb SD
Official 7" touch screen. Please people get one of these this project is so much easier if you break down and spend the money for it.
I had a UBlox 7 usb gps receiver that I could never get to work even outside navit.
I opted for Ublox NEO-6M GPS Module and it is working wonderfully with a LOT of tweaking.
I only have to put the radio module (si4703) back in and test everything together.

Well that doesn't make sense I only have 1 amp in my car. How are the 2 sources being tied together?

This has been discussed several times in the forum. A search on the forum for 'radio output' would answer your question. To make it short: you have to connect audio outputs from radio and Pi like shown here (Figure 4).

The radio never shuts off.

Not true! The radio is controlled by the carpc controller. There's no need to worry about!


I will be trying to see if I can get the tea5767 FM module working (as soon as I get my new one). I don't like the how si4703 is set up. The tea5767 has a sound jack and antenna jack makes it easier than having to remove a surface mount capacitor then soldering in an antenna lead.

I am going with ViewHD HDMI Audio Extractor with 5.1CH Decoder for sound as I have a 5 channel amp. I will let you know how that works out.

Hopefully it will still be at the link a few months down the road:
https://www.amazon.com/ViewHD-Extractor ... VHD-H2HADi

So far REAL good.

Thanks! It worked!

Is there a way to show the cursor of the mouse if I decide to connect one?

This is currently not possible without changing some code. But I will release an update to the skin in a few days, which will have a setting for that.

Hello Jack, firstly a big thank you for all the help through the Posts, I managed to get my System mostly running without having to ask as most questions had already come up. Some of them a few times, hahaha. Anyway, my question is regarding the next update, is this still in the Pipeline? If the current release is anything to go by I can imagine how great the upgrade will be. Anyway, thanks guys for an awesome Forum and a great project.

Hi MacNastard!

I plan to release the update this weekend. Had to go through some testing and bug fixing, so it took a bit longer than expected. But it's almost done now. It won't be a big update. Mostly optimizations and some bug fixes. A few new features are included though.

Of course you can install and use the current skin version and update when the new version is out. You won't lose anything, all settings, data etc. will stay untouched.

Hello friends,
I am facing with a problem and I may need some advice. I am using raspberry pi3 and waveshare 4.3 inch HDMI lcd. I installed carpc successfully and then I have placed advancedsettings.xml file in ~/.kodi/userdata and it contains ;
<advancedsettings>
<touchscreen>
<x_offset>-20</x_offset>
<y_offset>-20</y_offset>
<x_stretch_factor>0.1217</x_stretch_factor>
<y_stretch_factor>0.071</y_stretch_factor>
</touchscreen>
</advancedsettings>
( I used touchscreen calibration before setting up the car pc and found max and min x,y values. The resolution for the lcd is 480x272 and stretch factor values were calculated with this formula 480/x_max , 272/y_max)
When the carpc starts touchscreen is working great for 10 seconds and then boom cursor disappears and it is not working and it is also not working in the desktop.

I have created 99-calibration.conf in /usr/share/X11/xorg.conf.d/99-calibration.conf but nothing changed.

I also modified touchscreen_axes_calib as the same with the valeus in the advancedsettings.xml file.
As I heard advancesettings.xml is not working for Kodi versions lower than 17 so I tried to delete it and nothing changed so it seems advancedsettings.xml is not affecting anything.

Is there anybody faced with this problem and do you have any idea about fixing it ? thanks..

Hi guys,

I have trawled and trawled this topic and many a google searches and i can not seem to find a fix to my problem :cry: ...

I have: RPi 3 and a 64gb micro sd and a 8gb miccro sd, have followed this set up about 6 times trying different combos of installs and nothing seems to work. im not willing to give up on this!! :idea:

My issue is....I have a fresh Raspbian Jessie install, followed this tutorial to the dot. once i do a reboot the carpc splash screen loads up, takes about 2-3 minutes of loading (no idea why) then simply goes into a black screen and nothing!.

I activated SSH before i did the carpc install and puTTy still wont let me SSH into it..

any help would greatly be appreciatted!

Note:
adjusted the GPU = 256


UPDATE: Tried a different Micro SD all working, now to change the language...
