While neither the Samsung nor the Sony Ericsson were yet functional demos, we took the opportunity to play with the Nokia 701 and the paired XAV-601BT. Needless to say, we were presented with a brilliant and functional interface that allowed quick and seamless access to the maps, music and telephone features of Nokia Car Mode. The 601BT ($549) features a removable face and a 6.1-inch WVGA touchscreen, while its larger brother, the 701HD ($699) sports a 7-inch WVGA display and HD radio. The interface was a bit showy, but also offered quick navigation through the relevant apps and features.

The most unique element of Mirror Link is the ability for smartphone manufacturers to throw their own interface onto a car stereo. For instance, it seems that Sony will add quick links to traffic, parking and weather (along with the standard navigation, music and phone links), in an interface that's somewhat reminiscent of Windows Phone Metro. Meanwhile, it appears that Samsung is going absolutely crazy with its implementation, which includes features such as calendaring, voice recording, email and, yes... Facebook. Admittedly, we're a bit weary of drivers updating their status at a stoplight, but that's not going to stop us from grabbing new car stereos this summer.
