I'm not fixated on google maps, but it certainly does do custom routing exactly how I want it to - on the computer. The problem is getting that custom route onto the phone and then it sticking to it (seemed to have lost the custom route a couple times for no reason and reverted to a fastest way back route).

But yes, it would be nice to create the route on the phone itself, for those impromptu rides I don't have a chance to plan on ahead of time on the computer. Bluetooth mouse is interesting, I've never tried to pair a mouse before with my phone. I just might try that to see what happens.

Still haven't looked up how to do custom routes on Endomondo but apparently this does exist so I think I'll be set once I figure out how. I always have that running while on the bike anyhow.
