Re: Sat nav
Smartphone and Google maps is horrible. I can spend hours waxing on about why it is, but I'll leave it at this. First, that setup is far too reliant on data connection of the phone. Second, Google maps plots out your route to get you there quick, which is so not the point on a motorcycle.
I've got a Garmin Zumo 660 and love it. It's very reliable and paired with a Bluetooth headset plus some MP3s loaded on it, it's an entertainment center as well. If the MP3 player isn't important, there are cheaper alternatives out there.
The 660 actually comes with a RAM mount system in the box that will work if your bike has round bars. I'm not sure on the LT, but my RT has flat bars so I had to improvise the mounting system.
