IMHO, you are both right in a way.
Being a software, hardware, and systems developer, I have come to learn that your knowledgeable customers expect their will be hiccups along the way, especially in a "first release" situation. Technology generally consists of many, many complex and integrated systems. If you think about software code as a tangible item, you could argue that there are hundreds of thousands, if not millions of "parts" to any software system. Now, add the parts from the actual audio hardware, USB hardware, and interfacing equipment. What you end up with is millions of individual components, each of which is man-made and is subject to fail - and when they do, can cause unpredictable behavior.
It is unreasonable to expect everything to work all the time. Your hot water heater can break down. your cable can go out. Your PC can crash. It's logical to think your car's electronics can glitch, too. When you stop and think about it - it's really quite remarkable that most
of these systems work most
of the time. It is truly a testament to human ingenuity.
That being said..
The following devices may be connected to the USB port and controlled by the infotainment system.
. USB Mass Storage Devices
Not all iPod's or USB Mass Storage Devices are compatible with the infotainment system.
This information is way beyond deceptive and vague. It is the manufacturer's responsibility to inform the end user of the features, functionalities, and restrictions of the product they are delivering. I know that if MY boss were putting out this manual (he is very worried about being sued over misinforming our customers) He would have listed the compatible iPod models and requirements for usb mass storage devices... at the very least. He might also have put some wording like "Compatible models subject to change - contact dealer for updated list." This way, when a customer sees their specific iPod model, they can feel rest assured their iPod will work.. and if they don't, they know how to find out for sure. If that feature is important to them, they'll move on. Nowadays, an iPod jack is a big feature to a lot of people when looking for a new car. People spend a lot of time and/or money on their iPods. Between the device itself, app downloads, music downalods, stickers, peripheral hardware, etc.. many people spend their entire day on their iPhone. They don't want to get into their car and have to turn the radio on, search for a song they like and sift through commercials.
