    @jrt.typo Sorry the XK is a different system so this upgrade wouldn't work


    I've not updated this thread for a while, but have been using my system and working on a few upgrades in the background. There are a few more people who now have a JagDroid system in their own cars, X-Types, S-Types and X350/8s


    Just a few points while I think of them now:

    - I've devised a new method of performing the audio aux-in mod on the CD player. I had found that sometimes when doing the SPDIF version of the mod (for Standard audio equipped cars) that there could be some interference induced (lots of clicking noises) due to the SPDIF cabling going up to the touchscreen relay board and back again. Now I fit an Arduino Nano inside the CD player with 1 relay (for Standard audio SPDIF cars) or 2 relays (for Alpine Premium audio Analogue L/R cars), which can be switched between aux-in and the CD audio by holding the CD button on the CD player. The back of the player is fitted with 1 or 2 phono sockets for aux-in, depending on audio system type and everything is now contained within the CD player so the external wiring is simplified and interference eliminated.

    - I now use a capacitive touch overlay as already tested by other users, advantages over the AR1100 resistive touch are that it requires no calibration, panel edges are already masked off in black, touch sensitivity is improved, and it has multi-touch capability

    - I use an 800 nits brightness screen @ 800x480 pixels resolution, which measured with a Lux meter shows pretty much the same max brightness as the OEM screen. Backlight control is integrated in the latest Arduino sketch and with a minor mod to the RTD video board the original Brightness control and Day/Night auto switching of the OEM system is retained.

    - I have installed a DAB+ USB module on my car, along with a Fakra antenna splitter which allows me to receive DAB through the existing antenna. Reception isn't as good as I would like, however the splitter I'm using is a passive one - active amplified ones are available which may improve reception.

    - I have installed a reversing camera with auto-switching on selecting reverse. Other users had already done this but thought I should really try it myself! This can be achieved simply by adding a relay with its coil in parallel with a reversing lamp to generate a positive +12v switched live on selecting reverse (Jag uses a negative switched system which means this addition is necessary) which goes to the RTD board and it then switches to AV2 when selecting reverse. A forward camera is also possible as there is a second AV input on the RTD board. I added shortcut functions to the sketch so that you can double-press REAR HEAT to switch to reverse camera at any time, and FRONT HEAT to switch to the front camera.

    Hi Ben,

    Following this project with great enthusiasm, looking forward to doing an install in my car. Would you say the project has reached the level of maturity where the usb dab+ could be used as a full replacement for the FM tuner? That would be my primary use and wondering what its like in aspects such as will it resume from sleep and start playing the last station it was tuned to? Also what would the experience be from an android "cold boot"? Can the dab channels be changed by steering wheel control?

    Thanks,

    Jon

    Hi Jon, sorry for the delay replying.

    I'm not a heavy user of DAB myself, although I have added a DAB stick to my system as I've had lots of people ask me about it. It works really well (caveat regarding the antenna below), and this process has become much easier recently as the DAB app is now available in the Google Play store rather than having to download the .apk file manually from a website and install it.

    I tried an antenna splitter to get the DAB signal from the existing FM antenna mounted to the rear screen, but I've not been very happy with the signal. Another user has recommended this antenna: https://www.dabonwheels.co.uk/produc...twig-dma-1004/ , although you need a steel body car as it's a magnetic mount (so not an X350 for example!). I'm sure other decent antennas are available, but I've not tested them myself.

    In my experience the DAB app will continue to play the last station it was set to, and I seem to recall seeing an option to get it to start the DAB application on bootup, but I haven't looked at this myself (I prefer to start my music manually, just a single press in Car Launcher, depending on whether I want Spotify, USB music, etc). It certainly works with the steering wheel controls and you can change station by pressing up/down on the steering wheel.

    Thanks Ben, that sounds very encouraging! Point noted about getting a decent dab antenna. I'm in no hurry to start the project, so will wait until you've finalised / published your latest design with the new capacitive screen, Arduino Nano etc.

    Kind Regards,

    Jon

    Has anyone tried some Bluetooth Tyre Pressure Monitors paired to an android app on the modded head unit.
