RSNAV

[Tyintegra]

I just got mine installed last night and it works great!

The only issue i have is to that one of the radio removal tools (cheap ones I got off eBay) is stuck in the radio. I tried pushing the "button" on the side of the radio (where the key is stuck behind the face plate) and it didn't work.

I tried all of the other suggestions online with no success.

Does anyone have any suggestions?

[lnferno]

I’m still getting these Fault codes. Also when I get a text if I’m listening to the radio I have to switch back to six to be able to hear it. Is that correct ? Seems like I can’t use the radio and CarPlay together with our switching them back and forth.

I'm getting that same infotainment error code.

This is normal, you can't hear anything from CarPlay while you are on radio, this is how audi designed their audio processing. We can invent a way to overlaying CarPlay sound over radio, but that usually causes loud volume issues so we are not doing that.

I'm getting that same infotainment error code.

03389 is when both AMI and AUX is active. In principle, Audi designed not to use Both AMI and AUX at the same time. Bur if you disable AMI, you are going to lose factory BT. Since, it's not critical error, I hope you woudn't mind about it. It's just preventing two different audio signals mixed in one channel wihtout a proper mixer, but by installing our interface, your MMI port is already disconnected, so there is no risk of mixing signals and giving stress to MMI headunit.

Any idea of when the RSA-12305 (10.25" for MMI3G) will be out/available?

Just let you know quickly, I have no idea. The board is ready, but CANBUS supplier's techies are not coming to our factory to integrate the MMI buttons with the system. It's their proprietary system and we have no access to tweak it.

[Borg54]

Can you describe more about the issue? you see only the chinese language screen and nothing happens?

Here is a video:

Also, I sometimes get no audio when I plug in the phone. Everything looks like it is working but there is no sound. I have to turn off the car and unplug the phone and start over.

I have an iPhone 7 Plus

Thanks there are a lot of discussion in C7 forum about iPhone 7 Plus issue. Simply, use Amazon Cable and do not use an USB extension.

I am using an OEM Apple lightning cable plugged into the RSNav USB outlet.

I am not using the USB cigarette lighter port supplied in the kit

I know it's crazy, but OEM Apple lighting cable is not good enough. Go to the C7 forum and I explained the problem, and there is testimony as well. Apple OEM cable is missing a shielding and it makes a huge difference.

I can’t use an amazon cable because it doesn’t work with my charging dock. Is this limited to iPhone 7 Plus?

What about my other issues?

I appreciate you being so responsive on here

This is limited to only iPhone 7+, other models work great. It's purely due to the USB controller IC in the iPhone7+ which is B grade stuff.
What other issues? connectivity, sound intermittent everything is related to USB connection error. Technically, iPhone 7+ has an issue with 480mbps highspeed connection establishment, so it's dropping a lot of signals, thus iPhone 7+ is keep trying to reset the handshake and pushing audio stream to BT etc. This was huge issue within Apple too and I read a gizmodo article that it was escalated into Apple's Engineer level. If you search with 'CarPLAY iphone 7 plus USB' you are going to see a lot articles about it. We will try to compensate this problem by increasing USB V+ power delivery, which is effective measure, but it's really iPhone 7+ hardware problem. Compensating has its own limit. Also DC step up regulator or USB signal enhancer could be applied to stablize the connection, but then again, it a bit feels like 'why should We fix it, not apple?' frustration.

Thanks for the detail. I worked with Apple for a long time and they can make some brilliant but also some very frustrating choices.

The other issues I’m having in my video. Do you think those are because of the iPhone 7 Plus? The screen not loading properly etc? It isn’t just an audio issue.

That is the typical USB 2.0 signal degradation symptom.
CarPlay uses a lot of USB traffic so 480mbps connection is mandatory. So the reason that the screen is not loading properly is
- USB 2.0 480Mbps High-Speed handshake is established and iPhone and the interface try to exchange packets.
- However, the signal degradation in the communication terminates 480Mbps connection, but the interface tries to keep listen to iPhone as the handshake is done.
- Thus, the screen is not properly loaded.
- It's the duty of iPhone 7+'s USB IC to maintain the communication since iPhone is the host in this case. But the ic is to say 'B grade' stuff.

If we capture the signals using a lab equipment, it would look like (a) where there is a lot of noise, whereas (b) is an error-free signal.

This can be compensated by increasing the power delivery or well-shielded cable against EMI noise. Nevertheless, it's curable only and only if the host sends out proper and strong signal in the first place.

[a4android]

The truth is the interface is nothing but an H.264 video decoder with Apple's encryption chip, sound processor, AP, Rom, and RAMs. It's iPhone that processes and send 'video' signal to be emulated in MMI screen. However, since there is the bottleneck of data traffic in USB channel, the 'video' cannot be played properly. Thus, it's why both CarPlay and Android Auto is so much dependant on cable quality. It wouldn't be matter if every platform moves into USB 3.0, but CarPlay and Android Auto does not support USB 3.0 yet. So no manufacturer produces USB 3.0 interface.

Daniel , just wanted to say thank you for all of the detailed information. Mine has been working well, and this is my 2nd CarPlay System so I know the system is not perfect. I last used it with a Pioneer NEX in one of my trucks.

Side note iOS 11 has really upped its game with apple maps. I’ve been using it in traffic the last two days and I’m impressed. It’s not WAZE yet , but it’s pretty good.

Really was interested in this until I saw I have to physically plug my phone in for $400. Price just doesn't seem justified especially when the entire 10.5" Nav system is $650.

Hey Daniel,

sorry to hijack but i tried PM'ing you and you havent gotten back to me. Not sure how else i can look for you since original thread is gone but im interested in the 2G MMI unit for a 2007 Q7 and i know you said 2-4 weeks about 2-4 weeks ago. Was wondering when that one will be available along with the 3G MMI one for S4's.

It's not allowed to discuss price in this thread because it's prohibited by the forum rules. Nevertheless, Audi Smartphone interface for B9 S4 is 400 Euro option, and the device also supports HDMI input for ATSC-B TV tuners.

For 3G MMI, it's readily available, but for 2G MMI, we are considering to manufacture or not. 2G MMI is very costly to develope, because it's proprietary display signals and most interface.

oh man, i was looking forward to the 2G. The Q7 is really outdated and it has no form of aux input or bluetooth streaming. Maybe throw a 3G MMI in it and then your Android interface

[R3.]

I have one last question. What handles the D/A conversion ? The MMI or does the RSNAV box have some sort of DAC built in ? AUX I assumed was for a 3.5mm analog input so I’m just curious what handled that process , if it’s the RS unit do you know what DAC it is ?

Thanks

For the smartphone interface, DAC is Cirrus Logic CS4344 24-bit 192kHz DAC.

[R3.]

Right but the lighting cable does not send an analog signal correct ? I don’t think it’s possible which is why the small lightning headphones have a tiny DAC built in.

Correct. For example, Apple's 3.5mm adaptor, it has DAC in it.
Related to our device, the music stream from iPhone to our interface is a digital signal. That's partially why you don't get any audio with iPhone 7+ and the original lightning cable due to unstable USB controller ic. In the case of the digital audio signal, if an error is detected, then the DAC gets mute.

So the MMI unit is the end DAC ?

It's the amp where the end DAC is. MMI has ADC for the external input. However, no body knows what digital audio format audi uses so we cannot directly tab on the digital audio channels.

I too am holding out for a 2G MMI solution rather than a retrofit to 3G. Please Keep us posted Daniel on 2G options.

I literally factored availability of this interface into my decision to buy a 2013 Allroad this past weekend and placed my order right after getting the car home. No, it wasn't the deciding factor, but it was certainly a nudge. Now, PayPal's pulling their famous "punish successful sellers" antics. That's about par for my luck though.

Anyway, I started out with an aftermarket touchscreen CarPlay radio in a B7 and then drove a B9 for several months before passing it on to the wife and taking on her VW CC. I put an RCD330 in the CC which effectively means I went from touchscreen Carplay to MMI knob, back to touchscreen. In my opinion, the knob's the way to go. The touchscreen seems like the more modern, high-tech option only until you've experienced the magic of not selecting the wrong thing three times in a row as your car skips across uneven pavement.

Looking forward to getting my interface and making my otherwise awesome Allroad feel more modern in the entertainment department. I'm also hoping, based on my understanding of the way it works, that it can be configured to be on by default. That is, the interface takes control of the LCD whenever there's an iPhone connected. I get that I'd have to leave the MMI on aux, but that's really my intent anyway.

Quick question about this device and future AndroidAuto compatibility. If we buy the kit as it is on the RSNav site today, will it be upgradable to support AndroidAuto, or is an entirely different device/sku required?

Also I've noticed that a lot of people on other sites that have AA on their GMs, Honda's, etc... constantly complain of new updates to their Android phones affect reliability to their OEM AA. Will this solution continue to receive updates/fixes as time goes on?

Thanks for your time, extremely excited about this product and looking forward to it breathing new life in to my A5!

The current hardware will be upgradable and will be the same hardware for AA. We will provide updates and fixes continuesly. However, it's usually phone firmware problem in most cases. OEM AA or our interface is basically dumb boxes that is hijacking infotainment screen and audio and throwing out what is sent from the phone. We are doing our jobs to compensate this by tweaking USB controller firmware if it happnes. But, like iPhone7+ issue discussed above, it's usually certain phones to be blamed, not these interfaces.

There is something for Concert, but I don't think it doesn't worth your money for the display has low resolution.

How will upgrades work? Through the USB port on the device and a thumb drive? Or will we use our phones to push the updates?

Okay, hopefully my last question.

Will the AUX change required for this device prevent AMI adapters from working on a 3G high? For example I have a 3.5mm AMI adapter that I also use for other devices? Will I lose that capability with this device?

You are going to lose it. This is to prevent mixing analog signals without a proper sound mixer, otherwise MMI headunit's analog to digital converter will die of stress. There is a way to get this problem around by adding a third party mixer, but it turns out degrading sound quality too much in general.

[M/M's Dad]

Daniel, congratulations on a great product. If memory serves me (from the previous thread), this unit is not yet compatible with MY 2016 A6 (C7). Is that correct? If so, any plans/timetable as to when it might be? Thanks.
