and now obviously is quite cheap, with it forget junction view and 3D buildings, but 8 hours battery and replaceable by user,rugged, waterproof and multi-mode .
Can receive routes from Mapsource.... no new gadgets, but all the old good features and more

Hi Catymag!. sorry for my english.
I have a nuvi 510 (same 500/550) I use in boat and car every weekend, without problem, in my modest opinion is not wonderful but is good GPS. (with some limitation like work with tracks)
I have two doubts
1) In firmware revision from version 3.10 to 3.20:
Garmin added support for raster maps. I not understand the finality or posible use of this.
2) Acording specification I understand don't have capacity of use Custom Maps (KMZ). o JNX. But with patch firmware or "alternative way", is posible to do that ?
Thanks!
