The 730 costs more but does it do anything that the 430 can't?
Does the 430 have traffic rerouting as part of the nav to avoid traffic?

There are several threads which detail the differences around here.

The 430N needs the separate Connectivity Package for voice bluetooth. Whereas the 730N has such built-in.

The 430N has Garmin navigation, which is really well supported in the 'net. Whereas the 730N has Harmon navigation.

The 730N has "dead reckoning", which allows it to continue to navigate when the looses it GPS signal (like in urban canyons).

The 730N has the breadcrumb feature. I thought it was silly. Then I went wheeling in a place with lots of trails that lead various ways. I love the feature now!

Main differences:

430N:

Requires connectivity package to have Bluetooth
Uses Garmin based nav
Can upload custom POI's with Garmin's software
Does not support voice control of nav
Does not have dead reckoning for lost signal coverage
Can only view nav or radio, not both at once

730N:
Bluetooth built in
Uses Navteq/Harmon based interface (which I personally prefer)
No ability to upload POI's
Voice command of nav
Has dead reckoning coverage
split screen view of map and radio

Also note that the included bluetooth on the 730N reduces the connectivity package down to $160 or so since it's already included in the price of the 730N.
