This is long winded - bear with me... I currently run a Zumo 660 and a GPSMap 60Csx and have been considering updating to a new device. I've had both of these devices for years. Long before Spotify and Pandora were popular and readily accessable via smartphone apps. My current uses are as follows: BMW R1150 RT Husqvarna TE610 Land Rover Discovery II and Volvo 960 I have a motorcycle mount hardwired into the Land Rover and the audio output from that mount connected to the CD input of the stock stereo. I have a automotive mount in the Volvo. However, both of these vehicles need a new stereo, or the stock stereo repaired, and I could incorporate a line input in either, or replace the stock units with bluetooth capable head units. I have the BMW setup with a Touratech mount for the Zumo and utilize the MP3 player to send music to my SENA SMH10 and I also link my iPhone to the Zumo so I can see who's calling and also have the ability to initiate phone calls from the Zumo (although I seldom ever do this). On the Husky, I just have the GPSMap 60Csx set up with wired power. When riding it, I link my cell phone directly to my SENA SMH10 for music and phone calls. I either utilize the music player on the iPhone to play my personal music library, or stream Pandora or Spotify (although I don't have a subscription to either and the ads can get annoying). Given the fact that I have an unlimited data plan, the need for the MP3 player in the GPS is not as important to me as it was when I bought the Zumo 660. In addition, when I bought all of this stuff, I was still piping sound into my helmet via a wired connection with a StarCom1 Advance and had my cell phone connected via a hard wire. So, now that I use the SENA SMH10, I'm not even sure how important having the phone connected to the GPS is to me anymore. My goal would be to simplify to a single device that would meet my needs for on-road navigation and off-road navigation with a particular focus on tracks with a large amount of points. The Zumo 590 or 595 would certainly be the closest to what I have in the Zumo 660 and add some functions that I don't have with Spotify pass through and weather via the smartphone link. They do a pretty decent job of handling tracks. But the screen still leaves a little bit to be desired and the mount is not as rugged as the mount for the 276Cx. The 276Cx is much better at handling tracks and would be similar in operation to my 60Csx. The fact that it will provide onscreen alerts that show who's calling, who sent a text, and will support weather data provide the essentials of the cell phone link. The glass screen and buttons, as compared to the touch screen are very attractive to me. I thought I had my mind set on the Zumo 595 until the 276Cx came out. A couple of questions... 1. Do the Zumos have support for shaping point data like the 276Cx does? 2. Is the screen on the new Zumo series enough better than the 660 that it is a noticeable improvement? 3. Is it reasonably easy to find points of interest on the 276Cx? Can you browse categories like you can on the Zumos? 4. Is it reasonably easy to enter addresses on the 276Cx when typing using the buttons rather than the touch screen on the Zumo series? 5. Are lifetime Map Updates available for the 276Cx, or would I have to pay for every map update? Any thoughts that would help drive me in making a decision, particularly from anyone who has experience with both, would be appreciated. I'd asked a little about this in the 276Cx thread, but after continuing to read that thread and giving more thought to how important (or unimportant) the MP3 player and pass through of cell calls is, given the SMH10, I'm still torn.
