Link to iPhone map App from HTML page

Question

Is there a way to link to directions in the iPhone map app from a html page?

We're placing an add in an iPhone app which will link to a mobile page on our website - we'd like to add a directions link, thus far google searches have been unrevealing.

Answer 1

A link to http://maps.google.com/maps will automatically open in the map application

You can set a destination address (daddr) and start address (saddr) in the link:

http://maps.google.com/maps?daddr=San+Francisco,+CA&saddr=cupertino

You can see some more options at:

Answer 2

Here is a javascript function that creates the link:

function mapLink(myAddress) {
    return 'http://maps.google.com/maps?q='+escape(myAddress);
}

This works great on the iPhone.

Answer 3

If you use the standard link that would display a map in the browser, it will automatically open in Google Maps on the device. That includes links that show directions.
