A bit off-topic, I admit, but:
I haven't played with it much since buying my Scram in October (such is my disappointment with the Tripper) so maybe there's been some drastic improvement in the past couple months, but I really am not impressed with the Tripper's function. I'll say it does seem, from this forum and other sources found Googling and YouTubing, that a lot of the herky-jerkiness, telling-me-to-turn-500 feet-too-late, and "stuck on spinning compass" issues are being resolved with newer versions of the app, where said newer versions are available in India but not yet in the U.S. Being in AUS you may have access to a better version of the app than we have here in the U.S. (only version 1.4 on the Android store at the moment), so YMMV based on that.
Where I'm going with this: I got the Tripper for free with my Scram, and I'd love to see a way to delete it or install something better in its place. If you're going to be paying out of pocket for the unit and then paying someone to install it (or even just spending a nice afternoon cursing at it in the garage while you do the install) you may be money and time ahead just going with a nice smartphone mount or purpose-built motorcycle GPS unit.
