I thought I'd share my setup. This is the first car dock I've ever had but was eager now with the BT Stereo clip. Like many others, I didn't want it on my windshield (would actually be too far away) and wasn't thrilled with the prospect of sticky on my dash. Also, not a great place for the dash anyway.
After reading this thread I decided to check out
Proclips and get the one that goes over my vent to keep it cool. The one I was looking at was ~$30 but I wanted to do it right. Then they were gonna charge $8+ for shipping! F that.
I hit up Amazon and found this
Vent Mount for Garmin nuvi at $5 with free shipping (Prime.) I figured if it sucks then I'm out $5 and I'll go the proclips route. Turns out I'm thrilled with the vent mount.
It's about 80 degrees in KC and after driving around for 20 minutes with full sun exposure, the phone was actually cool to the touch with AC on low. I'm very pleased.
Here are some pics:
