Kristan, like many sensible and awesome people, was excited when GPS maker TomTom produced a limited edition unit for fans of the BBC program “Top Gear.” The biggest draw: the recorded voice of Jeremy Clarkson, the show’s lead presenter and an internationally beloved contrarian jerk. Clarkson’s voice isn’t available for separate purchase from TomTom, at least for American consumers. Oh, no. We have to shell out $269 for this spiffy satnav, and that’s what Kristan did. It turned out that the unit….wasn’t all that great. But the final insult came when it failed, and TomTom sent a warranty replacement of an inferior unit that contained no Top Gear content and required an additional $60 fee to reactivate the GO LIVE that Kristan had already paid for.
