Yelp Data into Navigation search

Would be great to be able to search for restaurants and business in the Sync Navigation and pull in Yelp data. This data could be pulled via a smart phone / tethered phone into the Nav environment and would provide a much more rich user experience by highlight places that have better reviews and maybe coupons (that I could get SMS'ed to my phone)

The data would be a lot more currently if pulled via a data connection then over a yearly subscription update. Also using Sirius is not a good option as it is to expensive and one way data path.
