AVIN AVANT 4 from hell!! Any insight is greatly appreciated!

[10013289]

Yo!

I recently grabbed the AVIN AVANT 4 unit for my 2002 x5 (without navigation) and it has been kicking my ass.

*sorry in advance for lots of words and poor grammar- I take pictures, words are hard, haha!*

I was nervous to attempt this install due to my lack of patience for anything electrical- so I brought the car to my local sound place with a good reputation. A few hundred dollars later the unit is in and looks great, but the sound cuts off after 30 seconds, and they forgot to install the CarPlay dongle. Thankfully I didnt leave before checking and we were able to schedule a time to come back for revision.

When I got home I popped the unit out and noticed no IBUS module- AVIN forgot to include one in the order. I hopped on with support and had a new one in 4-5 days.

Fast forward to round 2 at the install shop- this time im sticking around to aid with any Q's that can be searched through the AVIN support database. We got the IBUS in, app installed, checked all wiring, and eventually threw in the towel after coming up short again and again. We also pulled the IBUS module due to the misalignment of the settings that made the lights flash all crazy and the windows roll down when I locked the car, that was wild! This was solved eventually after digging and re-selecting the car type in the factory settings tab.

Also- we were unable to install CarPlay again due to AVIN forgetting to include the 3-USB harness.

After several hours digging and back/forth with AVIN support- they're going to send a new power harness, as well as the usb harness. We'll see how that goes when they arrive. *fingers crossed*

I noticed in several tutorials that there was a DSP button on the lower left of the IBUS app- mine didn't have that. After contacting IBUS directly, and a re-activation of my license I now have the DSP button, but the sound still cuts out, only this time I can get more sound by pressing the DSP button. Each press allows for about 30 seconds of sound.

One interesting note is that when the unit first powers on the sound quality is great and loud! But when I hit the DSP button and it kicks back on it's at about half the volume- I imagine this has something to do with the DSP controls or the EQ?

Also- there seems to be a "digital clicking" noise coming from the rear where the subwoofer is- the sound works when this clicking happens, but I imagine when everything is working properly that clicking won't be happening all the time? Admittedly I don't know much about this kinda stuff and I'd usually leave it to the pros, but unfortunately I can't find any that know about this specific system- the shop I take the car to said they don't do this kind of thing, and recommended me to the sound place that had never seen this unit before. (womp)

I've been trying to dig and find something similar to this but can't seem to find anything out there with a non-nav unit. According to AVIN I don't need the long cable that connects to the rear of the car. If anyone has any insight that would be greatly appreciated!

I'm really looking forward to getting this thing working- that first 30 second sample sounds great!

ALSO- here's a 3.5 minute video for complete context if anyone is interested: https://drive.google.com/file/d/1DiF1AfSGPqVKgKhFtBqGCF1XDwnGdPi1/view?usp=share_link
