I use Pandora about 95% of the times in my Terrain. No occasional sound problems. No static.
The only trouble I have is an occasional Bluetooth connection hangup when first starting up. (Had this problem with 4 different phones, so I'm pretty sure it's a bug in the Intellink and pretty sure GM won't fix it.)
