I was disappointed when I couldn't get my Garmin Nuvi to pair with my Sena 20S headset. Tried pairing to phone and phone to headset, but no joy. I've been putting off getting a Zumo for some time due to the cost. $270 for the Zumo 665LM (refurb.) seemed to be about as good as it gets, so I ordered one. No disappointments. It's a solid unit and it comes with EVERYTHING. Not expecting this, I had ordered some bits to mount it to my RAM mounts. Didn't need them.
Pros:
- A complete package with everything needed for MC and car mounting
- Lifetime maps!
- Bright display
- Unit feels solid
Cons
- Power Cable:
0- Wasn't long enough to reach from dash to power block under seat. Had to add a few feet.
0- There are so many connections on the cable, its ridiculous. We're wireless these days. They should offer/include a cable with just power. The connection for the XM antenna would have been better on the unit instead of the power cable for my purposes.
- It's an older operating system/interface. I like my newer, Nuvi better, but it's okay and will work fine.
- Plan on getting a microSD card. Internal memory is pretty much maxed out with the native software. Can't load MP3s or custom routes. An exhaustive internet search reveals a 16GB limit on microSD card size, although the manual is moot on this. Also, advise getting a fast (class 10) card or you'll be waiting for data to load, so they say.
- Pairing: I got a real education here. You can pair your phone (iphone) and the gps to the Sena headset, but only one of them can be primary (stereo). The other is secondary (mono). There are not less than six possible configurations. Each one contains a compromise.
- Sirius XM: At the time of purchase, the Zumo 665LM, includes XM Radio capability and was cheaper than the 660 without it. I ended up getting a subscription to enjoy this feature, but... the 665LM does not get all available channels. It appears to be limited to about 170 of the hundreds of available channels. If I'd have known that, I would have gone for one of the cheaper packages or none at all. However, since I paired the 665LM as a secondary device, I listen to XM through an app on my phone in order to get better sound quality. Note that there is no way to change channels through the phone app without going through the screen on the phone so if I want to listen to something else, I have to pull over, remove glove and change channel through the app instead of through the jog dial on the headset. bummer. If I had it to do all over again, I would have skipped the whole XM Radio fiasco altogether.
- Sound: So I'm listening to music through my headset via the iphone. Volume is near maximum and quality is good. Then the gps chimes in with directions... and nearly ruptures my eardrums! I have futzed with just about every possible setting and have yet to solve this. Same thing happens when I receive an incoming call. The volume of the phone ringing and subsequent call requires turning the volume on the headset way down low. I realize this is not a fault of the gps. The Zumo hands off volume control to the headset and tells you so. Wish I could find the magic setting that will even everything out.
Overall, I'm happy with the purchase and will sort the issues out as time goes on.
