I just got my 2015 Volt, and after driving a Honda Insight, and two Priuses for the last twelve years, it's a change. I've always had nav before, and i didn't buy it for the Volt, partly because Volt owners don't seem impressed with it, and partly because, in recent years, i have relied more on my phone than the onboard nav. But i'm interested in how 2015 Volt owners mount your cellphones when using them for nav. The windshield seems to slope too far away for an effective mount, and the top of the instrument panel seems too textured for a suction grip there. Does anyone use a cupholder mount? if so, which one? Thanks. I appreciate any help.
