I have a slipgrip holder for a Samsung Galaxy S4 in an Otterbox. I used this in conjunction with a stem holder. http://www.techmounts.com/products/radar-detector-mounts.php?page_function=detail&product_id=139 Was great for using a dashboard app, navigation, controlling musc to my chatterbox. This was a great setup that allowed me to keep my phone in the case. I've upgraded my phone. Looking to get $20, shipping priority mail would be $5.
