Amazon.com offers the TomTom Car Kit for iPod touch, model no. 9UOB.017.02, for $19.99. Shipping adds $5.58, so it's best to pad your order over $25 for free shipping. With padding, that's $3 under our mention from a month ago and the lowest total price we could find by $48. It features a built-in GPS receiver, charging iPod dock, built-in speaker, and compatibility with the 1st-, 2nd-, and 3rd-generation iPod touch. Of note, it doesn't include the TomTom U.S.A. for iPhone / iPod touch App; it costs $49.99. That's $10 more than our mention of this app last month.
