In another thread, where I was describing some easy ways to work around the internal memory limitations of the (somewhat long in the tooth) Zumo 550 GPS, another forum member suggested to just "man up" and get a Zumo 660/665 rather than deal with the memory. As promised in my reply there, this is my totally subjective description of why I feel that, even with it's age and limitations, I still prefer the Zumo 550 for regular touring use on a motorcycle over the 66X series zumos. Feel free to weigh in on why you feel the same, or contrary to my position.
I do own and regularly use both a Zumo 550 and a Zumo 660 GPS on my motorcycles. Here's how I see that they compare to each other:
Things the two GPSes do equally well for me:
MSRP is exactly the same for Zumo 550 and 660
Weight difference is negligible (less than 1 oz)
Contrary to what others have said, I can detect no speed advantage for one or the other.
Both are IPX7 waterproof
Both will run a pre-programmed route about the same way.
Both will Bluetooth to my crackberry cell phone (or any other phones that I've tried) equally well
Both will play MP3 music, navigation prompts and cell phone audio through my wired Starcom1 intercom about the same
Both have removable/replaceable batteries, with lives that make it useless without actually wiring to the bike's power.
Both will run the Garmin 24K topographic maps for when if I venture offroad, although the 550 actually displays the contour lines better and the 66X will display contour shading.
Zumo 66X Advantages over Zumo 450/550
Current Garmin "state of the art" product. (will possibly be supported by Garmin for a longer time)
Wide screen format (of questionable value)
Larger internal memory (3.6GB vs 1.2GB)
A2DP bluetooth stereo capable
Will index more MP3 files at once
Programmable info area (can choose what displays in the map corners - elevation, speed, time or distance to turn, etc)
Will display the speed limit (if it knows it) and indicate if you are above it.
Does "junction view" (which I actually dislike. I'd rather just see the map all the time)
Zumo 450/550 advantages over Zumo 66X
Considerably brighter display screen
More map detail (even when zoomed in, the 66X is severely lacking)
Multifunction hard buttons (touchscreen only on 66X)
Screen navigation easier when underway (66X requires delving through multiple "levels", 550 is sequential/circular screen navigation)
USB port easy access (behind battery compartment door on 66X)
SD card easy access (also behind battery compartment door on 66X)

Why I prefer my Zumo 550 over my Zumo 660
I do not see the value of the wider screen. The direction you are traveling is up/down on the screen and that is the same dimension. If I could change the display presentation to portrait then I would see that display as an advantage. I've actually sent a suggestion to Garmin to ask them to include that feature on some future software version. Especially for running topos/offroad, that would be a very nice thing to have.
The larger internal memory of the 66X can be pretty easily overcome (for me) by the use of SDHC cards on the 550 negating that advantage.
I do not use the A2DP bluetooth output (yet) as I do not have any A2DP capable headsets.
The 1000 MP3 limit of the 550 is not much of an issue, That equates to ~83 hours of continuous music (1000 x 5 minute MP3s), but you can always (easily) swap the SD cards and have a fresh 1000 titles to listen to.
The better map detail level of the 550 (when zoomed in) is a big advantage.
All of the above things are "software features" that could be changed by Garmin, if they so chose. And if they corrected some of these issues it might swing the balance over to the 660. But, the superior display screen brightness & contrast (does not wash out in sunlight as easily) and the multifunction hard buttons and navigation are features of the 550 that can never be migrated to the 660. At this point in time, I still prefer my 550 over my 660.
