I just traded in my 2014 RAV4 for a 2015 Sienna SE since I needed more space for carting my dogs around. My phone (Samsung Note 3) connected without a problem in the RAV4, but I cannot keep it connected in the Sienna. It connects initially, but after about 30 seconds, it disconnects. I can manually reconnect it, but the same thing happens every time. It simply will not stay connected. I can start a phone call when it initially connects, but it will disconnect while I am on the call and I have to switch to talking on the phone. I have taken it to the dealership, but they had no idea why it was doing this. The service person who was helping me connected his iPhone and it stayed connected, so it apparently has something to do with my phone. But why did my phone work with the RAV4 one day, and then not work the very next day with the Sienna? Anyone have any ideas?
