Definately.. although, being a recent TT7 convert I've had to also install GPSgate. If you're using this there's a couple of useful forum posts about using a Mortscript to run it, so it opens GPSgate, then TT7 to reduce the drain on the battery.
You can also set GPSgate to turn off when idle.. it'll take you a bit longer to get a lock, but it'll save you running to your nearest phone store to get a charger to "replace" the one you just threw out the window
