Oh, and also I'd suggest bringing along a external battery pack to charge your phone, etc. On the Defender we rented the cigar lighter only put out a few amps at best so while driving our phone would maintain it's charge level but never actually charge up to full. Not a huge problem as you can pull up and grab a drink/lunch somewhere and usually plug in but a battery with USB plugs would be helpful for sure. We used the heck out of our phone for nav, campsites, reviews, etc.
