Drop some requirements...? The combination trackback+CF+autorouting is
killing...

The Quest can do UTm, trackback and autorouting, but has no memory
cards. The 276C can do it all but has Garmin cards. Magellan probably
has receivers that do everything, but autorouting (in a decent way,
since their routable maps seem to s*ck).

This is my point

I have a GPSmap 276C

I want autorouting plus technical navigation features plus standard
memory - all reasonable

Garmin can give lots of options for the first and the last
requirements but all in a dumbed down package

All marine models have the Garmin datacards... because that way they
don;t have to produce CF cards with maps unlocked to one specific GPS.
Pro: you can swap Bluechart maps between mulitple units. Contra: it's
more expensive.

You have one of the best Garmin receivers on the market right now, but
it has one drawback: the Garmin datacards. Not only are they more
expensive, they are also limited in size to (now) 512MB.
