New firmware?

$600 is wrong.
I’ve heard as high as $200 though.
Changes are minuscule between versions
Recommendation is unless you live in an area under recent construction wait 3 or 4 years before updating or not at all.

 

I think you are talking about the "Special Service Campaign J0D"

Read following thread. I don't have advanced trim, so I did not get the letter.
J0D - Prius Special Service Campaign | PriusChat

As far as Nav map update is concerned, just forget about it. Any phone app or stand alone GPS unit will do far better job than Toyota's (or for that matter most any car maker's) in car Nav system.

 

Actually I did. Once. It was in one of those car washes where you sit in the car and it pulls you through.
If it was a traditional full service car wash I would not have know about the problem.
My personal experience was the warning indicators and alarm sounds were disturbing.
I don't know if the car ever applied the brakes which would be the big issue.
I fixed my own car with Carista but it's going in Monday to get the official fix.
Right now my car disables the proximity sensors whenever in neutral. I don't know
what the Toyota fix does instead of this or in addition to this.
I can envision the worst case scenario for this problem being the car applies the brakes
and keeps them applied long enough so the car is no longer moving but the car behind
it in the car wash keeps progressing and rear ends the Prius. Not a good thing for both cars.
If you don't have a Carista or equivalent programmer you can make a note to always
disable the proximity sensors using the MFD Settings before you go through the car wash until you have the
Service Campaign applied at the dealership. I believe they are turned on again automatically after a restart of the car.

 

My numbers are the same, but my SAM ID is different. It’s BAAAAFXGGW

Am I out of date?

 

Lane departure and steering is non functional below 32(?) mph so that won’t be an issue is a normal speed car wash.

 

I never had a problem with the brakes or anything when I go in the car wash. They're beginning it was hard to get it into neutral. But I put it in neutral and the car just rolls on the wheels from the auto wash.. I now go to car washes that is automatic, drive in, stop. And the automatic laser Car Wash does it thing. Doesn't hurt the tires or causing your car to gey missed aligned. And no scratchs.

This is the dealer trying to put a big markup on the customer. Thanks, but no. You could likely call all the local dealers and get a much lower price. Or, just skip it. It's likely that the road in the other side of the country from you that changed a bit isn't one that you drive on.

 

I've had no problems with the bucket and hose in my driveway. Not a big fan of car washes.

 

The update in Special Service Campaign J0R is for the Clearance Warning ECU, not for the Navigation Receiver Assembly (radio head unit), so it’s not surprising that the latter wouldn’t have a record of it.

As far as I know, the only way to tell if the J0R update has been done is to use a Toyota Techstream diagnostic system, or equivalent, to retrieve the version number (“Calibration ID,” in Toyota’s terms), shown in Techstream under Advanced Parking Guidance/ICS/Intuitive P/A. For the Prius Prime, the Technical Instructions for Special Service Campaign J0R document (available by subscription to techinfo.toyota.com) says the new Calibration ID is 8934F470307, which replaces 8934F470303 or 8934F470304.

 

They're trying to gouge you. The update should be $179. It comes on a micro-SD card and is user-installable, so no additional install charge. But really not worth it unless you're dead set against using your phone or a stand-alone GPS. My experience is Toyota's map updates are already a year (or more) out of date on the day of release.

 

As pointed out earlier, there are a bunch of independent computer systems on the Prime, each with its own firmware, so when one is talking about a "firmware update", one has to know which system is being discussed. The firmware version info shown on user displays is a very small subset. It used to be that all it took to work on cars was to be a competent mechanic with a standard set of wrenches and screwdrivers and such. Now one has to also be a computer tech with access to expensive computer diagnostic tools. And the Prime is at the high end of this computer sophistication.

 

I just got mine updated today at Frank Toyota (National City, Ca) for $140. (which is still pretty high IMHO. I am trying to find the change notices.

 

You can turn off the sensors when in neutral using Carista or similar ODB software.
