Hey guys, I searched and didn't see a thread about this and since it's a new product, figured I'd start one. I've been waiting over a year for Garmin to come out with a new and improved Zumo 665. Instead Garmin gave us the 350 LM which has some improvments but is missing other things? I'll go over the differences here: <<< Zumo 350 LM <<< Zumo 665 (new) Garmin Zumo 350 LM vs Zumo 665: 1. The screen and dimensions are about 5% smaller on the 350 LM but with the same resolution, both weigh the same. 2. Battery life is up to 7 hours!! (you give up other things though) The 665 is only 3 hours... (no big deal if its mounted on your bike.) 3. 350 LM has lifetime updates (which is what the LM stands for) with "nüMaps Guarantee"whatever that is? 4. No 3-D landmarks view (the 665 has this) If this is what I think it is, I like my 3-D view. 5. Can save up to 100 routes (vs 20 with the 665) ...meh 6. The new 350 LM has "Traffic Trends" which seems like it could be cool so you'd avoid rush hour traffic possibly? 7. 350 LM does not have XM radio?? Why would they remove this? 8. 350 LM has Garmin Locate which marks the spot you were when you took it off its mount... meh. 9. 665 has "photo navigation" that can read geotagged photos...meh 10. 350 LM will tell you which services are at the exit ramps. This seems very useful. 11. 350 LM has an alarm clock. Could be usefull if you are riding and need to remind yourself to do something... 12. 665 has downloadable custom voices while the 350 LM does not? Why would they not let you download a better voice? 13. 665 has a picture viewer...meh 14. The 665 has an MP3 player and Audiobook player but they left this out on the 350 LM. I liked this option for the 665. 15. The 350 LM has a trip program for your PC. 16. The 350 LM can work with gloves on!! (I'm not sure if the 665 will do this too?) 17. The 350 LM just came out so I'm not sure the Touratech lock will fit it's more rounded shape. 18. The 350 LM uses some different map program called Basecamp or something that I have heard people complain about... Overall, the 350 LM has some nice additions that would be welcome on the 665 but it's missing too many things. The 665 has XM radio and the ability to play audio books and MP3s... I'm not exactly sure how both the Garmin Zumo and my I-Phone would all tie in together into the Blutooth of my headset? I could potentially use my iPhone to play XM radio (if they have some sort of antenna or puck thingy for use with it?) otherwise the iPhone streaming XM radio from the internet would be a waste. If the iPhone can make up for the lack of things missing on the new 350 LM then you can enjoy the benefits of both, otherwise, I'd stick to the 665.
