After about six months of use and while it was still under warranty, the TomTom iPhone Car Kit Mark purchased failed. The onboard GPS booster and Bluetooth that are the entire point of the device stopped working. Some highlights of Mark’s struggle with the company: TomTom initially wouldn’t replace it, claiming that the warranty was void since they no longer make the product. Then they sent Mark what was clearly another customer’s return–a scratched-up unit without power cords. They claimed that they couldn’t send a power cord because Apple makes the cable. Because Apple manufactures black car-to-mini-USB cables.
