Anyone have an Audiotec-Fischer...
....MATCH (or HELIX in another car) amp try the HEC/MEC Bluetooth module. I have the MATCH 7UP BMW amp in my car and am wondering if it's worth adding the Bluetooth module.

Make sure your phone supports aptX, I don't think Apple does for example (could have changed since I last checked). Otherwise looks like a solid solution. I have the URC.3 remote installed which I really do like, if you're looking at adding that as well.

Good point! I have a document with my iPhone 7's spec.s Thanks for the tip.
BTW, that "broken pin" was actually just pushed back into the connector. I removed the cover and pushed it back where it belongs and straightened the other pins. Haven't tested it, though. Update: the iPhone 7 does not support aptX. Drat! I owe you 1! Update #2: it doesn't seem like any iPhone supports aptX. Last edited by MarcoZandrini; 04-10-2020 at 02:47 PM.. |

Re: the BT module it will still work but won't sound great, just transmit at regular BT quality dummed down by the phone. Your 2018 doesn't have auxiliary input in the armrest does it? I went through this whole mess with Viffermike help a few years ago, my 2016 with a lossless player in the armrest was the path of least resistance back then.

http://store.kokkia.com/kokkiai10lap...connector.aspx It doesn't get the best ratings on Amazon. I don't think the d2a converters in the factory system are that great, either. This would bypass the faxtory system by BT'ing directly to the MATCH 7UP amp. Why is nothing simple anymore? |

I think Astell and Kern (sp???) might make something like that but better quality. The factory converters are not good, you're right. That's why the Aux In is such a big improvement.
Doesn't your amp have an Aux in? Easiest thing to do may be run a cable up to the armrest and get a FiiO to leave in there. You might also need the Match remote to toggle source, not sure.

Actually, I'll have to look at the manual, but I don't seem to remember an aux in. That's why I was looking at the BT module. Anyway, an aux in would rely on the D2A converter in the cable that plugs into the lightning port. I don't think it's a very good converter, either. ARGH!
I'm now adding sound deadening to the trunk. The next steps are the doors and the sheet metal outside the rear seat. I'm even thinking about removing the front fender liners and putting the stuff on the metal fenders that protrude into the engine compartment. ARGH!!! |

Unfortunately you're at the nexus of cost cutting meets convenience meets most people don't care and are happy they don't need to plug their phone in.

Apple just launched the new iPhone SE might be worth checking to see if aptX support. Since you've got a 7, might be similar to me with the 8 where the SE makes sense for an upgrade. It's basically the guts from the newest 11 shoved into an 8 case and still has fingerprint versus face security. I'm ordering one as soon as they're available Friday morning, I've been waiting and waiting for them to launch something with fingerprint and home button.

I got an email from Doug Dobson about the USB module. You can program the amp so that it uses the USB module only when a signal is present on the USB cable. Otherwise it uses the factory harness as its input. So, I emailed the seller in the UK to cancel the order of the URC.3 remote. I'll let you know what happens.

OMG
I just finished adding the MEC USB module to the Audiotec-Fischer MARCH 7UP BMW amp.
OMG!!!!!!! The sound is so spacious and full. I can hear every instrument and every voice so clearly and perfectly. And my hearing is lousy. I used the BMW tech info system to learn how to remove the part of the console and the rear HVAC duct (www.newtis.info). Basically, the rear bottom seat cushion and the left bolster (sits between the fold down seat back and the left interior panel) come out. The "C" pillar cover comes out too. You definitely need the instructions to do this right!!!! It's all in section 51 of the TIS. The hard part is routing the USB cable from the console to the amp. Getting it under the carpet between the back of the console and the rear seat area is a real PITA. I used a very thing coat hanger and twine. as note, it's a royal PITA. The USB cable has to be at least 10 feet long. I then used a laptop with the Audiotec tuning software to configure the amp. I set it up so that the amp automatically switches to the USB input when there are data on the cable. One other thing. I have an iPhone so I needed an adapter that converts lightning connector to a USB connector. The one on the apple store in $40, but I found this on ebay: https://www.ebay.com/itm/Lightning-t...4AAOSwjLxelZcy . And this has a charging port while the apple adapter does not!!! I have been mod'ing the audio system in my bimmers since the late 1980's and I can say this has been the best investment in upgrade audio I've ever made!!

Update
Well, it seems the iPhone 7 doesn't play well with the AF USB card even with a genuine Apple adapter! So, I then bought the AF Bluetooth module for the amp. Worked for a while and then when I started to play a song the left rear speaker would pop. Contacted Crutchfield and I was sent a new BT module. Same thing. And then the BT module stopped broadcasting its presence. Crutchfield sent me a new amp. Work for a while and the issues returned. I re-installed the AF USB module and bought a Fiio M3 Pro digital music player (www.fiio.com/m3_pro). I had to run a 15' long cable with USB-C at console end and USB-B mini at the amp end. Finally, it all works!!! Dark Side of the Moon as .wav files is unbelievable!

I see you used the Apple USB Lightning Adapter when you were using the USB Card. What happens if you plug your iPhone into the USB Card via a basic lightning cable plugged into a USB-A Female -> USB-Mini Male (like this) and not using that Apple Lightning USB adapter? I’m curious does it work at all? Last edited by shaguar; 11-30-2020 at 12:44 AM.. |

Here's a link to the spec sheet of a $43 DAC from TI. It's 24 bits wide and 256k conversions per second. https://www.ti.com/lit/ds/symlink/da...ouser.com%252F |

One question: where did you get the 15' cable connecting your amp and the Fiio? I have spent a little time looking for exactly this cable and have not found it. |

Marco,
Do you mind sharing your amp tune if it’s not a hassle? I also have the Eton components with the Match Amp/DSP, and I feel the tunes on this forum are leaving something on the table for these speakers. |

Tuning the amp is fairly straightforward. I haven't used all of the software's capabilities but I'm very happy with the results. I basically zero'd out the center speaker's output.
I've attached the AF tuning guide. |
