Any updates on whether or not this worked?

No more reboots for me after doing this.  I still have the error and loss of instrument cluster audio info on my Tacoma dash until I restart the unit but steering wheel controls work and audio doesn’t cut out. Apparently there’s a firmware now for Maestro RR for TO2 called reboot. You may be able to flash it without calling ADS, but you may need to give them your account username so they can add it. I haven’t tried yet.

hello mdgeek,

i have( 2 ) avic-w8500nex and (1) avic-w8400nex

i have 2 maestro’s rr and the other one TLC has no steering wheel controls. ALL the pioneers re-boot’s randomly with the latest software. as of 11/1/19  

pioneer wants me to send them back for service. - too much hazles and there is no warranty they will fix it. - i heard many they have replace them with new and they all do the same. 

one of the cars (my tundra) i drive on a daily basis and that is why i see it more frequently. the other cars are parked 90% of the time. 

my cars 

miata 2014 

tundra 2008

land cruiser 2000 no maestro 

mdgeek,

kindly keep your comments up to date on your modifications. i will try to call maestro and see if they can add me to the list of downloads. 

note:

i am happy with the nav stereos and i personally think this is a way pioneer deals with possible screen freeze issues. by rebooting to ensure the proper functionality since i never have issues besides rebooting. (just my wild guess) 

fyi

sometimes it goes for weeks without rebooting. 

thank you in advance for your comments

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.

hello all,  6/20/20

now that i am back and driving my pioneer avic-w8500nex in my tundra 2008 with JVL is rebooting more often. i tried to call support yesterday all day long but was busy. 

*just to clarify:

do i need to call them so they can push my new firmware called “reboot” and re-flash ??? 

would this fix the random rebooting ? and i will loose my steering wheel controls until i reboot myself?????

someone pls clarify because if this is the case then i radder let the system do it for me 

thank you all!

I have 8000, 8200, 8400, 8500, and 8600. never had a problem with reboots. I would check the installs. I haven't had a customer come back with reboot problem. they only come back for more questions how to use the radio. I would bypass all power connections from the modules.

Sorry, following up Again. 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! 
 

3 days in with the power bypassing the Maestro and no reboots, seems like it’s fixed!

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.

Agreed, mine hasn’t rebooted since I did the bypass.

Almost all RR's

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 ?

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.

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.

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! 

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.

I tried it a few times to practice on a spare wire of similiar gauge.

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.)

Looks like there is yet another firmware available for this: 

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. 

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.

Have not seen a single reboot or disconnect since installing the new Maestro.  I'm going to declare victory at this point.  It has been a very frustrating experience and I'm kicking myself for not replacing the unit much earlier.

For those of you who did the power bypass, are you still seeing reboots?

Sadly I've continued to have sporadic problems despite replacing the Maestro module (black screens, steering controls not working), though no actual reboots (which was actually less problematic than what I'm experiencing now).  I'm throwing in the towel and reinstalling my factory original unit.  I'll be selling my head unit and Maestro module (with the appropriate caveats).  

I still get Maestro disconnect warnings despite flashing the maestro and noticing that several updates have been released since I last updated it. Sadly, I continue to have “maestro disconnected” warnings where music stops playing and I have to hit play again. Has anyone replaced their unit with anything more reliable without these same issues?

how often do you receive a message
I get a message several times a week that MRR is not connected
