  1. AVIC-W8500NEX Sporadically Reboots

    Received a replacement Maestro unit under warranty (with no hassle whatsoever) and installed it today. Left the USB cable connected and tucked it under the dash so I won't have to pull the unit to reflash it. Fingers crossed but expectations low.

    I reflashed the Maestro at the end of July, but the firmware version was the same as what I already had. Other than reflashing, I don't know if there is a way to see what firmware updates are available.
  3. AVIC-W8500NEX Sporadically Reboots

    I finally had the opportunity to try this workaround. Since the pandemic, I have done very little driving. Last week I went on a 12-hour road trip and decided that would be a good time to try the Maestro bypass (and re-flashed it while I was at it). This clearly fixed the head unit reboot problem, but I did see one brief message that the Maestro unit had disconnected and one time where the steering wheel controls did not work for a short time. It is clear to me that the problem is with the Maestro unit and not the head unit. It isn't clear whether this is a problem inherent to all Maestro units or I just have a lemon (in which case I am clearly not alone). It may well be too late to exchange the unit, but I'm going to give it a try.

    Has the new firmware been released? I searched for any mention of it and could find nothing. Before I pull out the unit to try the power bypass, would be nice to know if an update is forthcoming. Unfortunately with COVID-19 and working at home, haven't been driving much, so don't get to use the unit very often.

    Any updates on whether or not this worked?

    Let us know if this helps. Not excited about pulling the unit out to reflash the module, but if it works it would be worth it.
  7. AVIC-W8500NEX Sporadically Reboots

    On occasion when the head unit reboots, I catch a glimpse of an error message on the screen, but it never persists long enough to read it. Earlier this week, the following message popped up without a reboot. I suspect this is the message that is being displayed during the reboots. This suggests the Maestro unit may be to blame (or perhaps the wiring harness).

    Ok, after a 12-hour roundtrip in my 2015 Highlander: Outbound leg, using CarPlay navigation + TuneIn app. First 3 hours, no problem. Stopped for gas. Reboot within 15 minutes after resuming trip. A second reboot within 5 minutes. No further reboots for remainder of outbound leg. Return leg, using CarPlay navigation + Pandora app. Reboot within 1 hour. No further reboots for remainder of trip. So, no real pattern that I can see.

    Still seeing occasional reboots with no identifiable pattern. I too am using the Maestro ADS-MRR with the T02 harness. I am also using CarPlay so that may be a factor. I'll be on the road for about 12 hours this weekend, so it will be interesting to see how it goes.

    The vendor kindly replaced the head unit but the problem recurred within a short time. Very frustrating.
  11. I recently installed an AVIC-W8500NEX receiver in my 2015 Toyota Highlander. Most of the time it functions normally except every 30-90 minutes it will spontaneously shut down and reboot. I have checked all wiring, updated the firmware to the latest version (1.03) and reset the microprocessor, all to no avail. Anyone else have this problem? Pioneer tech support was essentially useless. They believe the unit is defective and that I need to exchange it (what a nightmare it will be to uninstall everything - still waiting to hear from the vendor).
