I stopped by the Amazon Books store today to make an online return. In the middle of the store was a big stand fully dedicated to Echo Auto. A sales rep swooped in and told me just how easy it was to set up and use. He said that all I have to do is connect it with a USB cable to a cigarette lighter plug and pair it via Bluetooth. If I didn't have Bluetooth, I could plug in an AUX cable directly into my stereo. It all sounded so simple!
A day earlier, I would have bought Echo Auto on the spot. Fortunately, I read your post last night, and it didn't sound simple at all. Listening to the salesman, I skeptically raised my eyebrow and said, "I'll think about it," then left.
