Just thought I'd say thanks for this port.

I have a Garmin Nuvi, but don't always have it with me.

I had the older version of this app installed on my old phone. Did get to use it once or twice. Is very helpful when I don't have service; otherwise I would just use Google Maps.
I decided to try this on my Samsung Galaxy S3 running AICP 5.1.1. From the quick testing I just did, it looks to be working great. Now if I'm out and about and have no cell service without my Nuvi, I'm set.
