Entune: System not installed (after 5.1 update) - 2012 Prius v (lowercase v for the v wagon)

Download the software on a different computer. Use a different USB stick, and make sure it is completely blank. Transfer the files to the new stick and attempt a reinstall. It appears that the .txt file is corrupt, on your stick. Could be a bad decompression, failing hard drive or bum USB drive.

Also, Toyota should have a fail safe to prevent the update when that file cannot be open/accessed.

Hard to know if target is from the stick or your head unit. If the version.txt file is corrupt in the head unit, they can try to reinstall it, or replace the head unit if the firmware is corrupt.

 

I for one won't update mine until they resolve this or at least put out a new version. Seems to be a clear bug.

First, I would spend some time finding and documenting other people who had the same problem. It seems I have seen others on this site. Be sure to check the c and gen 3 forums. Contact those users if a resolution is not clear in their cases.

Second, tone it down with reps on the phone or at the dealer. Not everyone is as up to date as you might be. Normally they try to help and your not talking to some fly by night company down the street that may be trying to get to you. You don't need them mad at you, but call again after you do number one above.

Third, write well composed letters to the dealer, distributor and corporate. Not email. No threats, but make it professional in tone. This becomes real documentation that could be used later, especially if you send each certified.

Finally, even if you pay stay with it. Often Toyota will reimburse when they see a pattern hitting their customers.

 

I was able to download and install the firmware update without any problems. After reading about the problems encountered by triumpGuy and the ridiculous cost of navigation updates, I've decide my next car will be a base model without this connected garbage. Problem is getting a car without these built in apps is going to be nearly impossible to find.

 

I also have the entune update issue. Tried to install 5.1 from toyotas web site, an now entune is toast. Goes to installing 3 of 8 and hangs. I also tried to reinstall 2 different earlier versions with the same results.

 

I bought my prius V itech 2014. From melbourne. Dealer Australia. After driving 11hrs or so to my home in sydney. All the app arrow Right/Left. With all entune app suit disappeared next morning. Australia toyota is full of shit. We are treated with world class left over as New Tech. For us. . i got to two Toyota dealer they knew nothing of prius V itech and said, nothing (toyota link app suit) came with my car.. I send email to Toyota regarding my firmware update. I was told contact local Toyota dealer. As if they know everthing about this firmware of premium JBL GreenEdge navi system. Shame on them. I endup calling Toyota USA from Australia regarding firmware update. And the lady said "sorry can't help you because of geo restrictions". If I ever knew this was to happen I would had standard V and saved 18 thousand dollars. Or any other car. This was my first Toyota vehicle regretfully...

 

I know this is an old thread. We purchased our '12 Prius v 5 in April and I still can't figure out Entune. Does the dealer need to change any settings since we're the most recent owners? We both have Entune downloaded to our iPhones but haven't been able to associate it with the system in the vehicle. Must we have bluetooth enabled on our phones for it to work? Thanks in advance for your advice.

 

Were you cable-connecting your iphones?

Enable bluetooth and bluetooth networking on your iphones, go to setup/bluetooth and enable bluetooth on the car. Pair the phones. You should be good to go.

 

I had the same problem - installed 5.1 using a flash drive, followed the instructions, it started loading and then stopped, giving me the message: ERROR: Unable tostart mmc driver successfully. Now it's caught in a nasty loop. Can't find solutions on line, just others with the same problem. Can I replace the "head" or radio itself?

 

Just killed my V model 5 Entunes. Did the current, 5.2 update, everything worked on the update, 8 of 8 successful, then it says Remove USB to complete update. Removed USB, now screen is black for a minute, nothing. Restart car and only have radio and climate. Says System Is Not Installed when I hit the Apps button.

 

put the usb back?

 

tried the USB again, tried download again, diconnected battery for 20 min, nothing worked. Going to dealer tomorrow.
I can't find the 3.2 version, or I'd try to install that.

 

please keep us posted, all the best!

 

3.2 is in this zip file but I am not sure you can go back in rev

 

Dealer charged me $135 to diagnose, to tell me it's not working (Duh). They had to do this, so I could contact Toyota HQ Service, which I did. Toyota HQ then gave me a case # and contacts local dealer. Luckily I video recorded my install, and screen saved my download page. Long story short, Toyota HQ said Head Unit needs to be replaced, at no charge to me. I'm at the dealer now, new unit is in with 5.2 s/w and same "System Not Installed" message is shown with pressing App key. They are diagnosing....
Also, when this originally happened my USB port stopped working. No data communicaiton. Would not charge a phone - my phone kept start/stop charging every second (maybe system was rebooting/looping - no constant power to USB por). So, no chance in hell of me recovering the head unit with new s/w (tried 2 dozen times, 2.3, 5.1, 5.2, different USB sticks, etc.).

 

Dealer replace head unit, after I spoke with Toyota HQ. For no charge. Problem was not fixed.
Dealer ran Diagnostics, and determined extension box was defective, so that was replaced no charge, after I spoke to Toyota HQ again.
Now system is working. However, it says software version 3.2. And I still have the Bluetooth off message Plus entunes does not keep running on my phone with the latest Rev.

 

I recently purchased a 2012 Prius v Five with Navigation but without JBL. I followed the directions to upgrade exactly as they were stated and now my Entune system is bricked. Nothing but AM/FM and black screen. When I hold down the Apps button I get "System Not Installed". Has anyone had success with the 5.2 upgrade, or figured out a way to get back from the black screen abyss?

 

bpasternak - You're screwed. Follow what I did and Toyota district service rep should pay for everything to get things replaced.
