Intro and Dynavin Android D99+ comments/questions
A quick introduction. After lurking here for a while and reading up on things, I purchased a D99+ Andriod version for my 2004 X5 (E53) from Jeff at J&T. I am pleased so far with the unit and aside from a few quirks, I have almost everything done with my install (pics to come in a day or two). Aside from the unit itself, I also added a backup cam (ebay Koolertron variety) to the trunk trim handle which was about as fun as I expected wiring-wise, but that aside it is (mostly) working as expected an I am happy with it.
So, here are my questions ... I did search pretty extensively around on the forums/internet for answers before posting these but nothing I have found as of yet has really answered them. Any input (preferably positive!) is greatly appreciated.
1) I have installed my reverse cam and I can see the video if I switch to the cam input, but it does not switch automatically when I put it in reverse. I have the system setting set for camera only. I did not run the ‘reverse’ wire because I thought that the bus sent that info and the wire was not needed. Am I missing something? I do have the cam wired to a switched 12v so that it is always on, but I did try unplugging the video feed, putting it into reverse, then plugging in the feed to see if it was triggered by the input signal and that did not seem to make a difference.
2) My steering wheel controls are a bit erratic. If I hit volume up continuously, it will either go up the first five or six times then stop for another five or six presses, or it won’t go up at all for the first five or six presses and then it starts responding. The same applies for volume down and track up and down. I checked the bus interface box and it is secure and trying unplugging and replugging without any change. I have pulled the bus interface box and reflashed it just in case - with the no-obc/no-odc firmware - but the issue is the same. I am wondering if this is possibly related to issue #1 above as well.
3) The touchscreen is flakey - from what I can tell only on the Andriod side. I calibrated it on both sides of the hardware, but when I am running on the android side I get unusual results. What happens is that the system will trigger a tap on the previous area of the screen, even if you are typing somewhere else – ie, if I type the letter “D” and then the letter “O”, the system will register another “D” when I press the “O” on the screen. It is not just the keyboard either – lots of times tapping the back arrow will result in the ‘last tapped’ point on the screen to be triggered instead. I have gone as far as reflashing the firmware with the latest stock version, but it is still happening. I have also tried to replicate it on the non-android side, but have not seen it happen there yet. Is anyone else reporting this type of issue, or could there be a HW problem on the android side of things? I can reproduce it pretty easy, so if a video example would help I can post one up.
One last comment to share was with the wiring of the backup cam from the rear hatch to the front. I was dreading running the wire under the carpet and all the way up to the front, including removing the seat and such as per the posts I have seen for other installs. My idea, which fortunately worked, was to just run the wire straight out the hatch grommet and all the way inside the passenger side headliner, then down the front passenger front pillar and behind the glovebox into the Dynavin. I'm sure I am not the first to do it this way, but thought I would mention it since I did not run across anyone else running it this way and found it to work pretty well.
I appreciate any comments anyone has on my questions and would be happy to try and answer anyone else's as well. Thanks in advance!
