They're both great units, but I have had Garmin units in the past and it would have saved me re-learning how to use a GPS. A lot of people prefer the Garmin unit, which is why it was ordered like that, I'm sure. Don't worry, the 730 doesn't have anything that the Garmin doesn't. The interface is just different (different software).
At least that's my experience so far, comparing my Navteq to my Garmin portable unit.
Thats not exactly true. Here are the major differences between the systems.
Major differences between the RHB and RER/RHR navigation radios
Chrysler Group created the RHB radio (430N) as a lower priced alternative to the top of the line RER/RHR (730N) navigation radios. The 430N is priced several hundred dollars less than the 730N - but it does not have all of the features.
The RHB uses navigation software by Garmin, while the RER/RHR uses navigation software by Navteq. The graphics and some features are different.</B>
When a vehicle doesn't have a clear view of the sky - such as in a tunnel or garage, or when surrounded by tall buildings - all navigation systems lose reception of GPS satellite signals. The 730N has a "dead reckoning" feature which enables it to estimate the current location until the sky is once again visible. (At start-up, it also remembers the vehicles last location, and immediately displays this estimated location until it can read signals for a precise fix). This is also known as "Enhanced GPS". The RHB does not have dead reckoning: it will display a question mark until it can receive GPS satellite signals and identify the current location.
With the 730N, drivers can program a desired destination using Uconnect Voice Command, while the vehicle is in motion. While the voice command is packaged with the 430N on most vehicles (and an option on the rest), it cannot be used to operate the navigation system - the vehicle must be parked so that drivers can enter a destination using the on-screen keyboard.
The 730N includes traffic information provided by SIRIUS; the first year's subscription is free. The 430N does not offer this feature. However, the 430N is able to receive the SIRIUS Travel Link service, with helpful information about weather, nearby filling stations and prices, nearby movie theaters and show times, and even sports scores. The RER radio cannot do this, but its replacement model, the RHR, includes the feature. Split-screen mode:
With the 730N you can view music and navigation screens at the same time.
