I use my phone for listening to my music via Bluetooth but also want to use it has a sat nav. So I need a holder for my 5s in an Apple leather case. Preferably want to use it in landscape mode but not that worried. But the main feature must be able to use it with the phone in its case. Don't mind paying a bit extra if it works and also does not damage the easily damaged Apple case. Any recommendations will be gratefully considered must be in UK. To be used in a 2011 Ford Fiesta if that helps.
