Ukulele Song - Onstar??

I'm trying to figure out the name of a song used in a recent (saw it during the olympics) car commercial. I don't remember exactly what kind of car was being advertised, but the commercial focuses on a dad putting his son into the car seat and then at the end using Onstar to figure out where they're going. The song has a ukulele and has been used in other commercials in the past. The only lyrics I know are the "oooooh, ooooooh" chorus line that goes along with the ukulele in the different commercials.

Thanks in advance for your help!

I'm fairly certain you're describing the song by a Hawaiian singer named Israel Kamakawiwo'ole, his version of the song "Over the Rainbow." You can find it on his CD called "Facing Future." It's been used a lot of places: TV Shows, ads, movies, etc...

You can listen to an audio sample here.

i have the song i don't think that's it but i apoligize if i'm wrong
