A U.K Web site has made the TomTom cradle available for pre-order at a cost of 99 pounds excluding VAT, or about $168.50 U.S., though a company spokesman would not confirm that price.

The price on handtec.co.uk, discovered by Daniweb.com, is the first possible glimpse at the anticipated product’s retail cost.

TomTom spokesman Kevin Carter said the company could not confirm the price, when asked by several sources. “At this point we haven’t publicly announced pricing,” Carter said, “either in the U.K. or the U.S.”

First unveiled by Apple at the WWDC keynote in June, the accessory kit will act as a basic suction-cup mount for the dashboard or windshield. Additionally, it will amplify the GPS signal, support both hands-free calling and music through the stereo system, and charge the iPhone from the car’s 12-volt port. A release date is not currently available.

The application is said to take advantage of iPhone OS 3.0′s support for true, turn-by-turn directions. The software will have both nation-specific and international maps from TomTom, will work in either landscape or portrait modes, and give voice directions.
