Well, those are great ideas, but I don't have a smart phone, and don't really want to pay for a data plan.
I have done some research though, and I've found out that the Nissan dash-mount GPS kit can be installed by do-it-yourselfers, and you don't have to buy the whole $300+ 999Q5-GU012 Garmin nav system kit!
All you need to do is order the Nissan universal mount kit - PG05-Charcoal mount part number is 999Q5-GU002, and it's $65. Then you can pick up a Garmin Nuvi for it on Ebay for $100! Much cheaper option than the complete kit, and you free up the power outlets in the rogue!
Here's an example of the install kit instructions I found online for putting this in a Nissan Cube:

Looks super easy to do. Rogue would have a different template included in the kit.
Hope this helps the rest of you! I'll do a write-up with pictures when I complete this!
