I'm all for it but are you saying I would need a ipad and a computer to get to get my route in the Garmin? I do carry a Ipad with me when on multiple day rides but not a computer.
Unfortunately, right now, that is correct.
Although, in practice, I don't find it that much different than when I was using BaseCamp. If you were to plan your ride in BaseCamp, then want to change it while on the ride, you would still need to have your computer with you. Now, you just need to bring your iPad also. For me, I always have my iPad with me. Using BaseCamp, I had to also bring my laptop. It's the same now but I have high hopes that at some point the laptop will sit at home and probably never be replaced.
I have not tried it but if you had access to any computer that had a USB port for hooking up your GPS, you could use that. Possibly a hotel computer or someone else's that you are riding with. The computer is only needed to transfer the file, you don't need BaseCamp.
If you have an iPhone you could leave your iPad at home. When logged into inRoute on your iPhone or iPad, you have all of the same data. You could make corrections to your route on your iPhone, email or transfer the file to a computer then to the GPS. The obvious problem would be with the smaller screen size doing a lot of work on the iPhone would be a little more challenging. I have an iPhone that I use and don't find it much of a problem. With the larger iPhone it is much easier.
I have asked inRoute support for more info on transferring files. While I have been using this app for awhile I am now focusing exclusively on using this app, the learning curve is steep. I will update with info I learn from inRoute. I don't profess to be an expert with inRoute, I am learning it as I go but I do have some experience with it.
