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.

Does anyone know to use the xtrons ibus app over bluetooth? I use android auto with pioneer headunit. I dont want to swap headunit now but want to occasionally control ibus.

I don't believe that's possible. You'd have to connect to the iBus network with something that would communicate to your head unit via Bluetooth and I don't think anything like that exists

I'm thinking of direct connection to the phone via bluetooth and not the headunit. Android auto is already using the micro-usb port of my phone.

Simple question now-how do you intall the ibus app into the headunit?
Do you download it to an usb drive and just select/launch it or do you need to get another app and change settings?

I've done a bit of research and nothing specific to the ibus app has come up.

I'm presuming it's pretty simple as I've not seen any instructions.

About to fit everything in the next few days, just wondering about things..
Thanks

This write up is awesome! Thank you for taking the time to lay it all out there.

I am literally pre E39 M5 ownership, picking one up on Monday. This looks like a tremendous upgrade.

I have always been a SQ focused guy. Can you shed some light on the on board quality and what connectivity options are available?

I love the ability to tap into the obc. I just want to get an idea how it integrates with a traditional system with aftermarket amps etc.

Also does it integrate with the new sound processor systems that are so common now days? And being android based can it control the processor on board with apps?

Can't wait to pick up the car and dig into which audio system it has.

Itís very simple. The head unit has a browser, you just navigate to the iBus app website and click on the link to download a zip file.

I did have to install an app from the Google Play store in order to extract the zip files, although Iím not 100% sure that was necessary. That may have been my own ignorance of Android showing.

Remember, this head unit is essentially just an android tablet, so anything you can do with a tablet you can do here.

I've gotten the HU and most of the cables. Just ordered RCA cables to run to the rear - I'd rather run them now than run them later. Doesn't look like the HU has an internal amp that could be used to bypass the stock amp.

I've got an old RF Punch 60ix - and had an old punch 4040 that I left in a car. Grr... would have been a very nice setup.

It's #2 on the list (the HU and getting the wiring done). Amps would be later... I'm assuming the HU install is a full day.

The HU has 5 audio outputs (RCAs) - front, rear and 1 for sub. I don't know the level or quality of them, as I haven't installed yet. I'm going to run 6 RCAs to the trunk, the extra for the backup camera. I don't see any wiring for an internal amp, though the HU has a sticker that seems to list the speaker outputs for the main plug, so I'm not sure if it has some internal power which could be used to bypass the stock amp. I was going to do this initially and just run the power straight to my new 2 way component fronts, as I thought there was an internal amp, but no such luck.

I'm going to get the HU installed first with the stock amp, but pull wires and RCAs for an amp at a later time.

My guess is the ideal setup for me would be a nice set of components up front (pick your poison), and either M-audio subs or the RF 10" free air solution that many have done. Find a nice amp to either pair with the 2 channel RF punch 60ix (circa 1997) that I have (punch 100 or another punch 60 or something), or get 1 amp that can handle 3/4/5 channels (maybe old punch 4080 or something new). Seems like there are lots of options for $150-250 range - I need to look and see if the newer amps are "better" or just "different". I know they can be smaller, and the output levels are drastically larger... I just recall a 40x4 channel setup with 1x120 on a sub was plenty.

Probably leave the rears connected to the stock amp and fade to the front, unless the 5 channel amps are similar priced. The tweets right behind the drivers head really messes up the stoundstage.

I'd love to do a fancy passive crossover with the single 2 channel amp I have to power the whole system... but I don't have enough knowledge / time to really get one built and tuned up front... and a second / new amp makes life easier in case my passive crossover doesn't work.

Iím no expert in regards to Sound Quality, but letís just say that people tend to leave the DSP system intact simply out of convenience - not because it sounds particularly good. Itís certainly not the worst Iíve ever heard, but given the complexity and the number of speakers involved, itís not exactly mind-blowing.

I suspect that the Chinese-built Android units will have marginal sound quality as compared to a top-tier audio manufacturer. Of course, thereís a major price difference between this and a $1200+ aftermarket HU.
