There seem to be quite a few products available for Techstream programming on Toyota vehicles from places like Amazon and Ebay. I see all types of reviews depending on what people are doing on different type of vehicles. Some would appear to have better software and more intuitive processes than others. I'm wondering if anyone has a particular cable/software combo that they find particularly useful and would recommend for the later Rav4s. Please chime in with your experiences and some info of what you have and where you got it. This will be really helpful for those of us who are novices at this. Thanks in advance.
