Accessory adds built-in GPS antenna, speaker
Apple has added the TomTom Car Kit for iPhone to its US online store. The accessory provides an iPhone dock and an adjustable mount that can be attached to the windshield or dashboard. A built-in GPS receiver helps to improve accuracy compared to using the iPhone alone, while an integrated speaker and volume controls can be used to amplify the turn-by-turn instructions or hands-free calling.
The TomTom Car Kit is compatible with the iPhone 3G or 3GS and can be pre-ordered for $120, although an estimated shipping time-frame has yet to be announced. The TomTom navigation app can be purchased from the App Store for $100.
