I tried to get my new Samsung Galaxy S3 working with my 2013 SV Leaf. I had something set wrong. But the cell phone support person wouldn't help me because that phone isn't on Nissan's approved list.
I corrected that setting and the S3 works fine with my Leaf's nav/audio now. The Galaxy S3 is a very popular model. Others have posted that it works well with their Leaf, too.
Nissan should add it to the approved list, so that others can get support from their cell phone suppliers.
