What is “rr”?

the meistro?

mine reboot and shuts off frequently as well

As I mentioned in my last post, I have decided to sell my head unit.  If anyone is interested, the eBay listing is at https://www.ebay.com/itm/125023716201.

I hope whoever buys it has better luck than me.  Really a shame - it's a great product when it works.

I have an AVIC-8500NEX in a 2014 traverse, and an AVH-W4500NEX in a 2016 cruze.

The 4500NEX started rebooting a couple weeks ago.  it was rare, but still annoying.  slowly its become more common until its every couple songs.

Here are some of the guesses i made to figure it out and the results of what i've tried.

1) Power:  connected a battery charger to the car, but the 4500 still rebooted.  (One of the times the radio rebooted is when the engine stopped at a red light, which stops the alternator, etc)

2) Source Check

1. Found that it did not reboot with apple car play or android auto (both wireless)
2. Did not reboot on radio, HD radio or SAT radio
3. Did not reboot on bluetooth
4. HDMI & Aux were untested (cables were not run when radio installed - shop offered but i said no)
5. USB01, USB02, and SD card:  Rebooted within 10 minutes on each!

Having narrowed the issue down to USB devices, i tried replacing with new SD card and thumb drives..  but the 4500 still reboots apparently at random regardless if playing audio or audio/video.

Finally, i took the SD card from my 8500 and put it in the 4500 and the sd card from the 4400 into the 8500...  no problems found, runs fine, no rebooting ON BOTH NEX devices...

Now its time to look at contents:  The SD card from the traverse has only 320 mp3's on it,  the sd card from the 4400 had misc data files, ms dos batch files (for creating text document of cd's and songs, etc), junk from work, etc...  i deleted all non media files but the 4400 still reboots.  

Deleted all wave, flac, mp4, and mkv files from the 4500's sd card (leaving only mp3 same as the sd chip from the 8500), BAM!  i think got it!

Which means (if i am right), the 4500 isn't powerful enough to handle lossless audio, or high bit length video for any length of time..

i would be interested in knowing if my results are applicable to your experiences!

It rebooted again.   And wow, i think my F bomb was louder than the radio FULL BLAST.

you know what i missed...  i missed wireless connections...  specifically apple car play.  Apparently after i had initially ruled it out, i didn't turn it off.

this morning driving my daughter to school, her iphone connected to my radio.  A few minutes later a popup that she left her air pods at home, and right the, the screen froze up for 2 seconds, then the crashed and rebooted...

Allow me to add this, not knowing if its relevant or not.  when the 4500 reboots, it has to "relearn" what is on the SD card, and (unlike the 8500), when the 4500 starts it always starts on the first song in the first folder...  i never thought i would get sick of ACDC, but if i do, it will be Pioneer's fault!  LOL
