It's my understanding that all 3 USBs are the same internal connection, so I don't think there's a specific one that needs to be used for the iPod/iPhone. None of the "stock" apps on the Xtrons appear to work with the iPhone, but I'd be willing to bet there's an app in the Google Play store that would do it. I need to spend a little time researching that one, actually. Too many irons in the fire lately (I have an E30 project that is eating up garage time lol )
Yes, the mounting plates mount to the sides of the stock opening. They have little "ears" that face front and the top corners (and top corners only) of the head unit attach. It looks to me like a solid case of "Friday afternoon before a long weekend" engineering.
I'm pretty critical of the mounting brackets, but I do need to remind myself that there's a price point to meet here and I suspect that custom-engineering a sweet mounting solution doesn't fit into that price point. For what it's worth, the Avin Avant 3 looks as though it mounts beautifully with the stock Nav carrier....
There is an issue with data transfer (sorry, don't know any details beyond that) on the Android 8 units. I believe it will be resolved with the next iBus app update, but no ETA on that as of now besides "soon".
I haven't noticed anything that's missing from the OBC, but to be honest I haven't had the stock system in this car for 3+ years, so I may be forgetting something. There are 2 current glitches on the main OBC screen:
- The conversion of fuel tank capacity to US gallons is not working (notice my 62 gallon tank in the pic below), which is supposed to be resolved in the next sw update
- The oil temp always shows "--" or "32". I'm afraid this one may never be resolved since the S62 oil temp data isn't available on the iBus network. I guess other E39s have a physical temp sensor somewhere other than the oil pan and that data is
available on non-S62 cars. You do have the option of just hiding the oil temp field completely, which is what I've done since this picture was taken. I figure we have the gauge on the cluster, so I'm not overly worried about that one.
