Nav update bricks stereo

Recently got a 50% coupon for Toyota Nav update DVD and since wife's been chirping in my ear about updating her nav in her 2010, I bought the update (version 95). Followed the directions and took the old DVD out (version 91) and put the new DVD in. DVD seated and I got a "Cannot read DVD" error on the screen, so ejected and put it back in and got the same error, and now the "open DVD" button no longer moves the screen up or ejects the DVD. Over the next hour the Stereo slowly degrades and finally stops working altogether, no audio, no blue tooth and the back-up camera even stops working. So off I go to Toyota and the try a soft reset, then they try power off reset by disconnecting battery and finally they hook up the Tech II and try resetting, all to no avail, stereo is still a brick. So they call corporate and are told that update 95 has too much data and overwhelms the memory in the stereo and eventually overwrites the entire memory including the operating system and bricks the radio. Stereo can't be reloaded or reflashed and has to be replaced. Although Toyota is replacing under a program, I'm still a bit skeptical. Anybody else ever had a problem with Nav updates or even heard of this?

 

Yes, Toyota is covering it, it's not a warranty, it's a "customer satisfaction" program. Been waiting 2 weeks for the new radio to get here though, so getting a little concerned.

12v is fine, 14.2v, car still runs and everything else works except radio.

 

Well, took Toyota 3 weeks to decide to do the right thing, but currently have a huge hole in the dash while the old unit is out getting refurbed. Now we'll see what happens when it comes back.

 

If you sign up for email alerts when you get service done, the local San Diego Toyota dealer network sends out email blasts with sales and specials. It was in one of the email blasts I got from Toyota of El Cajon.
