It's not so much that it's a TV. I suspect like many other modern
televisions mine (a Sony Bravia) is more like a computer with a big
screen than a traditional TV. Computers are everywhere, in the cars
that whiz by or at the local *$s where you stop for your mochachino
after a ride, for instance. Also, the fact that it can't reject noise
from such a common source suggests to me that it's probably got other
flaws as well. My previous wireless bike computer, a Sigma Sport
BC-800, worked flawlessly for several years. The db4LW was
effectively broken out of the box.
