Last week, Garmin issued separate but similar updates to its StreetPilot Onboard and NAVIGON apps. As it turns out, Garmin also released last week its long awaited Smartphone Link app for iOS.

Originally released on Android a little over a year ago, Garmin Smartphone Link is now finally available on iOS as well.

But as AppAdvice reader Kurt, who kindly brought the app to our attention, points out:

Unfortunately, its release only supports some of [Garmin's] new 2013 models. The 2012 models, which are supported on Android, are not supported on iOS.

Indeed, Garmin Smartphone Link for Android supports the following Garmin nüvi navigator models: 2475, 2495, 2595, 3490, and 3590. In contrast, Garmin Smartphone Link for iOS supports the following: 2497, 2597, 2797, and 3597.

Provided your nüvi navigator is of a compatible model, you can use Garmin Smartphone Link for iOS to connect your nüvi to your mobile data-enabled iOS device.

Once connected, your nüvi uses your existing mobile data plan to share various types of information. These include contacts, search results, favorite locations, and driving destinations.

What’s more, your nüvi is able to access Garmin’s suite of live services to provide you with different types of real-time driving information. These include weather conditions, traffic advisories, and parking spot suggestions.

Optimized for iPhone and iPod touch running iOS 6.0 or later, Garmin Smartphone Link is available now in the App Store for free.

Again, please note that the app is compatible with the aforementioned new nüvi models only.
