It's a lousy deal, IMHO.
Semson & Co. has a BU-353 receiver (highly regarded 'round these parts) bundled with iGuidance 3 for $159.99: http://www.semsons.com/is3mogpswiso.html
They also have a bluetooth GPS budled with iGuidance 3 for $155.99: http://www.semsons.com/ihiseblgpsre.html
If you want to go with MS Streets & Trips, the bundles get even cheaper, as low as $99.99, which is half of the $200 Garmin bundle you linked to. The software is far superior, as well.
