Hands Free has been the law in my state for some time and people who are fidgeting with anything distracting are more likely to have an accident. That has been proven. The Bluetooth worked fine for 7 years in my 2007 Lexus. It worked fine on my first iPhone 3g with voice dialing before it even had cut and paste. And four or five other phones from a Motorola Razor to an old Windows phone (they didn't even call it a smartphone) but the voice dial with Bluetooth worked perfectly.
It also downloaded my contacts in 2007. This is a "stick in the eye". Lexus isn't working on firmware on a 7 year old car even with the extended warranty. Bluetooth is a "standard" and they made it with specifications so that things like this wouldn't happen.
The old standard didn't change and though Bluetooth may have been upgraded from 1.0 to 4.1 to work better and more consistently, it was always backwards compatible.
More than 20,000 companies participate (Wikipedia) and this short area data transmission standard can be fixed. The problem is obviously Apple who has us all, by our commitment to stay with the IOS platform and other Apple platforms. We can't fight Apple and win. But not to give loyal customers a working system in nothing short of outrageous.
Heavens forbid, but when the first "class action" is brought against the company because this serious hazard is not being addressed, people will be jumping to get it fixed.
I hope we are "loud' enough so it doesn't have to be a vehicle accident that brings this to the attention of the people that can fix it. Apple changed something, Toyota didn't. We all know Apple can fix this. We just need to get their attention.
