Very few (older) models (like the Fortuna GPSmart;
http://www.pocketgps.co.uk/gpsmart.php) are like "bricks". ALL the other BT receivers are really small - like two matchboxes stacked together.

In addition to that, while the generics state that they are compliant with software like Tom Tom, when I go to the Tom Tom software site, they state that they do not fully support a CF or SD card type GPS.

That's not really true (must be some kind of standard disclaimer so that users can't sue the firm). As CF/SD GPS units communicate with standardized protocols, AFAIK ALL are compliant with TomTom. Actually, I've used my Pretec CF GPS card (before I sold it, due to the intolerably high power consumption) with TomTom.

Without an external antenna, yes. If your windscreen has any kind of evaporated metal, you'll end up buying and using an external antenna.

Is there that much of a difference in the SD or CF cards against the bluetooth bricks in a car?

If you ONLY want to use it in the car and also plan to use a car charger for the PDA, the CF/SD-based CF receivers are a viable alternative to BT units. If you want to do real hikings without any external power, I'd certainly go for BT models to avoid power problems and/or lugging around secondary/external batteries.

TomTom works with ANY card/ BT unit.
