On the plus side the uSD maps can be used in any GPS that takes the card.

I am much more worried about updated maps in my Nuvi for my motorhome for finding gas motels etc. I think I only have 2010 now. $85 is not a big deal for the convenience of pay and play. I am so far on the wrong side of Gore's digital divide that all the posts about unlocking maps is just something I want to avoid.
