LOL! Kills me; the people that talk about ugly and/or messy wires. Give me a break! The installation is only messy or ugly if you don't take your time and give some thought to wire placement. Then again, some folks don't want to be concerned with such trivial matters...
Anyway, not having to be concerned about inconsistent readings from either interference or low batteries, as well as the lower cost of wired units, tips the scales in their favor for me. I race so consistency and reliability of information are the most important criteria for me...
