I got nuvi 200w's for the clan for the holidays. I put my address and their respective addresses in each's unit, in a lame attempt to try and make it more personal... Used one for a few days to make sure it was user friendly enough for some of the less inclined recipients...
I ended up getting another one for myself because I liked it so much. It had everything I thought I needed and nothing I didn't (Mp3 player and speakerphone, come on...).
I would really recommend taking a look at the lower end of the range. Normally, I would be all over the high end of a product like this. I have always had GPS units for my laptop, and have had a topo unit forever for my outdoor excursions. I just do not see the need for a lot of the extra features that make some of the car units so expensive. I have traffic on my phone, and I mute my GPS anyway, so the street name pronunciation is not a big deal.
EDIT: BTW, they are Mac friendly 🙂
