TomTom have confirmed that their Car Kit – the optional accessory to accompany the TomTom iPhone app – will only fully work with the iPhone 3G and iPhone 3GS, thanks to a limitation in the TomTom application. The app’s limitation means that owners of the first-gen iPhone, together with iPod touch users, won’t be able to take advantage of the Car Kit’s integrated GPS receiver and speakerphone.
