I am using the Garmin version of the zumo 660 because it was slightly cheaper than HD but if I had it over again I would buy HD instead. The new model bikes are designed around the HD zumo allowing other important features to work with them. HD has put a lot of extra work into there's. I didn't see enough difference to get the 665. There is a lot of HD motorcycling info in it as well. Consider the HD model--it is worth the difference. The only other thing is it is hard to see display in the sun but not sure whether this is same on HD. Works excellent otherwise

I have the HD Zumo 660 and I'm happy with it so far. I used the HD fairing mount. It's easy to read most of the time. The sun glare makes it hard at certain times, but I'd expect that with any GPS in the open.

It updates the location quickly, the maps have been dead on so far, and there are many settings to tweak it to your liking. It did come with the free lifetime map upgrades.

 

I have used the HD Zumo with dash mount NIM module for almost 3 years. I use the SD card and download music to it. My wife loves it. The only problem is sometimes the glare makes it hard to see.It has been one of the best additions that I have added.

 

I have a 665 and really like it. I move it to my other vehicles when not using it on the bike. Mine is mounted to fairing. Don't bother with the interface module, just run a line to the Aux port.

 

Same with me, after buying the zuma 660, I saw that buying through an online Harley dealer that the ROAD TECH ZUMO 660 was about the same price. The normal Zuma 660 can't connect to the Harley speakers via the interface like the road tech does. For me that would have been a nice upgrade.
Still love my 660 and for $89 I also bought the maps for life. Where mine is mounted I have no issues with viewing in day light conditions.

 

WOW what it must be like where money is no object. I have a Ram Mount and use the Garmin 255 standard touch screen GPS with turn by turn instructions. If it rains I place a $ 200.00 baggie over the GPS and tie it with a 100.00 rubber band. It keeps the GPS working flawlessly and makes me feel like I spent 600 bucks on a waterproof model. I buy mine off of the net for about 29-49.00 refurbished with NEW maps. If they crap out, I chunk it in the garbage and pretend to cry for a while, drink a beer and go into my saddle back and get the next 30 dollar model out and use it...Garmin will referb the old one for about 69.00 bucks, but why, I can buy them from dealers for half that. Hummm that must say something about Garmin huh. Heck, I bet if I look I can find a refurbished HD model somewhere. Oh and lets not forget the HD logo on the product. Add another 100.00 for that.
Yep, it must be great to not have to worry about money. Like my dear old departed pappy use to say..."if you can afford a Harley you don't wory about the acessories right?
Mine works as good as yours does...and unfortunately better than the 2014 Infotainment big screen TV. Ever wonder why harley didn't use Garmin for their GPS on the infotainment system? Control...HD control.

 

Yup. Can afford it. Did it. There are many options out there. You do what works for you within your budget. I have hokey- pokey'd many things in life when the budget didn't allow me. Different point in my life now.

Lol.....man that jealousy must be a bitch.

 

I have a little different take on things than most of the opinions expressed so far. I liked my Zumo 660, but it was definitely NOT worth almost a grand, including fairing mount and interface module. Fortunately, I found mine on Ebay for about $350 used.

It suffers from a dozen small bugs that make it, in the end, not worth it. It's a touchscreen that works with gloves on. Great. Except it's fairly inaccurate, so you can never enter any text without correcting every fourth letter, which you'll typo. It automatically zooms in and out as you slow down and speed up. Great. Except it sometimes hangs for several seconds while it redraws the map in memory, so you'll miss important information like cross-street names while you wait for it to redraw. It has an interface module that allows it to announce instructions even when the radio or CD player are selected. Great. Except it also triggers the intercom while it does so, and at a louder volume, so those of us with helmet headsets get deafening wind noise along with it. (I eventually unplugged the interface module. Not sure whether it was a Harley or Garmin invention, but it truly sucked.) It has an audiobook reader app. Great. Except it only works with audible.com's proprietary encrypted format, so you CANNOT use it with common .mp3 audiobook files. It plays back MP3s as music files, though. Great. I was hoping for this to be a major feature, since the 700 MB capacity of the CD player was just too small, except the Zumo sometimes wouldn't recognize ANY of the MP3s on my 32 GB MicroSD card AT ALL, and took several restarts, followed by 10-15 minutes of music collection indexing, before it would play again.

I liked it, since I got it used at a discount. But I never loved it, never thought it was worth it, and when the 2014 Rushmores became available with all those problems gone... Garmin lost a map-buying customer forever. With my larger, more visually-appealing maps, flawless music playback, handlebar control integration and voice recognition, and one less device to **** with mounting/dismounting/securing at bathroom stops... the jealous little beeyotches can go right ahead and make fun of my "big-screen tv." I'm good.

 

bought zumo 550 january 07 always works fine,got the map for life but I think its impossable now on that model to load the entire us even with an extra storage disc...ive tried numerous times the last few year....

attached on a ram mount on handlebars,last year I moved it towards the back of the bars but this made it face up to much and glare issue a bit.this year i moved it where theres more room to tilt it down hopeing it will help...

btw dont use the other functions or the voice but still love the peice of mind that its rugged.
