More information was then leaked after TomTom's car kit was seen on the FCC website.
It looks like TomTom has decided to delay the release of the car kit until October to "deliver the highest quality innovative product." In a small note on their website's FAQ page, TomTom announced:
There are now many GPS apps available for the iPhone, but much of the excitement and anticipation for the TomTom version stems from its inclusion of a bundled accessory. We'll see how sales do when the car kit is released later next month.The TomTom car kit availability was originally planned for this summer. But we have decided to take some extra weeks in order to deliver the highest quality on this innovative product. So, the car kit will become available this October on www.tomtom.com.
