I'm finally ready to buy an 1800. I can buy a new '08 ABS for $18,800 or a '10 audio comfort for $19,100. My question is this...is the navigation system and ABS that important? Are there any inherent problems with the navigation system in the previous years? Could I mount a Garmin on the audio comfort model and have the same thing, minus the ABS of course? I'm really stretching my funds at the 19-grand mark and I can't quite cough up the extra cash for the '10 ABS. I haven't been able to find any new '07's anywhere. I'm not opposed to a used low-mileage bike either. How much difference is there in an '05-07 compared to the '08? I've owned a 1000, 1100, and '88 1500 in the past, so I'm comfortable with the wing, but not the newer 1800's. I would be very open to any advice available.
