[OSM-talk] advice for getting a newer Garmin nüvi car navigation device?

[Andreas Reuleaux]

I am about to get a newer Garmin n¼vi model for car navigation,
and want to use OSM maps with it.

I found several web pages, which suggest that in general
OSM maps on a n¼vi should not be any problem, but the models
listed on 

  http://wiki.openstreetmap.org/wiki/Garmin#N.C3.BCvi_series

e. g. seem all older than the models currently available in my
local fnac store, those are:

* n¼vi 3490 LMT, 300 ‚

* n¼vi 2595 LM, 200 ‚

* n¼vi 2545 LM, 150 ‚

* n¼vi 2445 LM, 150 ‚

* and n¼vi 40, 100 ‚

Any experience with those models? Any advice for getting / or
not getting a particular one? 

Will the fancier features of the higher prized models be available
to me at all, if I use OSM to Garmin converted maps
(which are, as I understand only Garmin format 1 maps)?

Thanks in advance.
