I didn't even know what a BeeLine was! So why do you have the TomTom on top of that?
Well, I've had the TomTom for ages, but it stopped talking to my phone a few years back, so it won't re-route, or do anything except follow the route I've laid out on the computer. However, what it does do is record my rides, and allows me to download them. It's also a perfect backup system for the BeeLine, which is a very simple interface, and very easy to make routes on the phone with. The BL has a very good basic navigation system, but the real beauty is to be able to drag the line between where you are and where you want to go, over any roads that tickle your fancy, by just using your index finger. The TT was a good unit before it stopped working with my iPhone, it's a well documented problem with no solution in sight. I used it to find my way to fun roads down south from NJ for years. This year I primarily used the BL, but there were times in the most remote parts of WV and NC where the phone GPS just stopped working and the TT was still picking up a signal. And it was good to be able to consult a map on the TT when again, there was no phone signal. Being able to see where I am and what's coming up can be useful at times. I admit to a certain level of paranoia, but I like to have solutions to problems on hand, if needed. I mostly leave the TT at home now for my more local rides, but on long trips it'll still have a place on my handlebars, just in case my phone or my BL stops working.
