    Default Bluetooth Issues on 2018 SL

    2018 Supra SL - whenever connecting via Bluetooth most of the time the audio makes a really strange garbled sound. It's annoying as this is the number one way I want to connect with music. Anyone else experiencing this? Already replaced the screen, looking to replace ICE module next.

    No issues for me Bluetooth.

    As much as i like wireless, i end up plugging in to charge at the same time. The audio quality is much better wired than Bluetooth. In my testing, i get measured distortion at full volume. Back it off one click from full volume and distortion disappears. I used a distortion meter when tuning my amp.

    The way i run it now is phone in holder, lightning cable and plug it in. I leave the lightning cable in the boat. And i use a real apple cable so i don’t have connection issues with some off brand ones.

    I agree with Ryann, USB cable > than BT.

    BT works fine, just better on the cable


    Also the phone setting (equalizer settings) greatly effect system performance.

    I set my iPhone to flat EQ and then use the boats EQ. Mixing both EQs was giving me issues.

    Good points Larry. You brought up something I forgot about. Don’t mess with EQ EXCEPT to turn down a specific range. Don’t turn them up or you introduce distortion. For mine, I lowered the higher pitch sounds.

    Also, my system hated when I changed the forward and rearward balance. It is ok to turn the bow speakers down, but the car-like function of pushing the audio balance to a different location was buggy.

    Agree, I found the preset EQ settings were best , I think I use the rock setting.

    The zone control works great and I have a few custom presets depending on what we are doing.

    If you’re on an iPhone, I’d suggest turning the EQ off completely. Even with it on flat setting if you change something in the head unit you can cause interference. At least on my ‘17 it makes a difference
