Well, I recently became the owner of my first Seat, a Leon FR diesel, so I thought I had better get registered and make a first post, as I gained quite a bit of info from this forum before buying the FR.
I have a Nokia E51 and whilst it would pair with the Media System 2 in the FR, it would not download the phonebook or recent calls etc. Incidentally my phone book is stored in the phone memory and not on the sim card. After trawling the forum here for info, I decided to see if there was a firmware update available for the E51 and if so, to see if it made any difference.
I updated the E51 to firmware version 400.34.011 via the Nokia updater and to my amazement it now works, phone book and all. I have multiple numbers stored under some phonebook entries and all these are displayed fine.
BTW. My E51 is a sim free model. Not sure if an operator branded model can be easily firmware updated.
