AppAdvice has teamed up with Magellan to offer you directionally challenged iPhone and iPod touch owners a chance to win a prize package consisting of a Magellan Premium Car Kit ($129.99) and a promo code for Magellan’s RoadMate USA ($49.99).

Magellan’s Premium Car Kit is able to transform your iPhone or even your iPod touch into a complete vehicle navigation solution. Its built-in GPS receiver is not only able to boost your iPhone’s GPS signal but also allow you to use your iPod touch as a full-featured GPS navigator.

The cradle is able to attach directly to your windshield or to your dashboard, and can be easily adjusted for portrait or landscape viewing. While mounted in the cradle, your iDevice will automatically be charged, so no more worrying about running out of juice while on the road. The cradle also features a built-in speaker, audio-out, and a noise-cancelling speakerphone.

Cradles can often be a pain to setup and even use since most are designed to fit specific iPhone or iPod touch models, but that’s not the case with Magellan’s Premium Car Kit. The cradle features an adjustable top clamp and back spacer that will ensure your iDevice is held safely and securely no matter what type of case or skin you have on it.

Magellan’s RoadMate navigation app is a great companion to the Premium Car Kit, although the cradle supports almost all other navigation apps for iPhone and iPod touch. RoadMate USA provides everything you could possibly need from a navigation app including turn-by-turn directions, lane assistance, POI search and sharing, address book integration, real-time traffic alerts (as long as coupons are enabled), and full multitasking support.
