Other than sticking your phone into the glovebox or center console the 991 series cars have no place (and certainly no good place) to put one. I suppose this is common problem on many vehicles but I’d had enough. After trying other solutions (i.e. a phone holder on my windshield) I was excited when Rennline released a 991 phone mount and decided to give it a whirl.
The Rennline system uses a ball joint that’s secured into place by piggy-backing on two screws holding in the PCM. You simply remove a trim piece on the center console and install the bracket. A magnetic mount secures onto the ball joint and a magnet is placed on your phone or inside your phone case.
I put some BHQ-blue vinyl over the magnet on the back of my phone.
The unit is well constructed and holds the phone securely. I recently got a new smaller phone and even with my far-left magnet placement the PCM screen is still badly obstructed by the phone. I think Rennline could have engineered the bracket to position the phone further to the left. Even with this limitation the system works well and is far superior to anything else I’ve found. Running my lightning cable from the glove box to the phone is fairly simple and unobstructive as well. Until something better comes along or Porsche addresses the issue I would recommend the Rennline magnetic mount to anyone looking for a place to put their phone.
The video below shows portions of the unboxing, installation and positioning of the various magnetic components:
5/20/2017 Update: After a few days of using the phone mount I can definitively say it works well. The location, aside from cutting off a slice of the PCM screen, is great. It’s easy to plug in, select music, use the maps, and even activate the voice control for music or to send a text (only when I’m stopped). Because my magnet is located at he bottom of the phone it’s quite stable when I’m pressing the home button which is helpful too.
