Made a jumper from the black/red wire to the red wire from the radio and capped the end going Into the RR per Maestro support. This will isolate the issue if it’s actually maestro related or radio related. Pretty sure the power goes directly to the radio now and not though the maestro. We’ll see if this fixes it. Still no reboots? I’ve had a few with the maestro and new WT7600NEX. What’s the best way to tap into that black/ red wire? I’d like to cut it and solder/ shrink wrap. I don’t think I have the skills to strip it back and not cut the wire like you did! Quote Link to post Share on other sites
Dizle Posted June 26, 2020 Report Share Posted June 26, 2020 3 days in with the power bypassing the Maestro and no reboots, seems like it’s fixed! Quote Link to post Share on other sites

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. Quote Link to post Share on other sites

Angey Joe Posted August 2, 2020 Report Share Posted August 2, 2020 I’ve been going crazy with this same issue. I’m so glad I found this thread! Thank you! I have a 2011 4Runner limited and the 8500nex and it reboots unpredictably. I’m going to try what Tired Hands did. Thank you! Has anyone been able to update their Maestro with the new firmware and did that solve the problem without having to redirect power ? Quote Link to post Share on other sites

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. Quote Link to post Share on other sites

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. Quote Link to post Share on other sites
H2OSUN Posted September 29, 2020 Report Share Posted September 29, 2020 So... after getting my 8500 Nex back from United Radio (they replaced the System on chip)... still having reboot issues. After reading here about the power wire and Maestro issues...i find the new firmware is updated from 3.3 to 3.8. I updated a few weeks ago... and after many hours of driving... no reboot. So far so good. I would recommend the firmware update! Quote Link to post Share on other sites
Tiredhands Posted October 1, 2020 Report Share Posted October 1, 2020 As a follow up, I spoke with ADS and confirmed the latest RR version for the TO2 fixes the reboot issue. Its version 3.1 for me. The jumper still works. Glad we solved this. Quote Link to post Share on other sites

I tried it a few times to practice on a spare wire of similiar gauge. Quote Link to post Share on other sites
H2OSUN Posted October 23, 2020 Report Share Posted October 23, 2020 So...started getting reboots again. Totally random...no one thing or event that each occurrence has in common. Will try the power wire bypass now. (Pioneer insists on doing the whole United Radio repair process again. Honestly, if I have to go another month with a big ass hole in my dash...I'm just throwing this thing away and going with another brand. Such bullshit.) Quote Link to post Share on other sites
H2OSUN Posted October 23, 2020 Report Share Posted October 23, 2020 Looks like there is yet another firmware available for this: MAESTRO RR ADS-MRR FIRMWARE ADS-RR(SR)-TOY01-DS (512) V3.9 HARDWARE RR (512) Quote Link to post Share on other sites
H2OSUN Posted October 23, 2020 Report Share Posted October 23, 2020 I updated to the 3.9...drove to the store for some trivial get the hell out of the house before I lose my mind crap...and stereo rebooted again. So, I called Maestro iDatalink tech support. A long story short (substantial electronics background)...if a power bypass is involved, it sounds like it is a biasing issue in the module. Meaning, at one point everything is fine, then there is a current draw in the system, the system reboots, and everything is fine again until the next event. Since there is no one event (using apps, changing apps, bluetooth, etc) that is causing it, and more or direct power seems to be the solution, then we need to find the issue/event using too much power. It sounds like the tech folks are running to ground the same thing. They said the 3.6 firmware should have solved it. Then 3.8 and 3.9 followed quickly after that. I am going to wait on cutting wires and give them a chance to figure it out. As soon as I hear anything...I will post it here ASAP. In the meantime...random reboots. :^( Cheers.

H2OSUN Posted October 23, 2020 Report Share Posted October 23, 2020 And by the way...stripping wires, especially in the middle of a run...use these. They used to be super expensive but have gotten less so over the years. Quote Link to post Share on other sites
