One of the members on the TT forum found a diagnostic cable that comes with a clone of the Toyota Techstream V7 software for $34. That's about $1500 less than Toyota's price. Here's a link to it:

I have one on the way so I will post a product review when it arrives next week.

 

It's a big save, but is the good as the original?

 

today the mini VCI arrived,
it's easy to use.
great.
