The TomTom Car Kit and the Magellan Premium Car Kit are two devices that fill the same very small niche. As we've seen in our reviews, these iPhone accessories solve the problem of where to place your iPhone while driving and navigating. Not content to merely hold your iDevice is place, these kits also feature integrated GPS receivers that enhance the accuracy of the iPhone's positioning, loud Bluetooth speakerphones that are compliant with handsfree laws, and 12-volt chargers that ensure that your iPhone is juiced and ready to go once you get where you're going.
Both units have been praised for making the iPhone much more useful in the car; and both have met with criticism for being a bit on the pricey side. So which one should you get? With such similar functionality and performance, we decided that it all comes down to form factor. With that in mind, we put these two iPhone accessories side by side to see how they stack up.
