Thanks Fobs...
Onto Auscruise right now, expecting a callback shortly.
In addition to Fobs' post I will put up pics of install and pricing etc. Probably gonna go with my local installer rather than stuff about with it myself... my tech savvyness could likely do the job but I'm just too busy with other stuff such as 2 high-end PC builds in the next week. Southern Car Care down here in Bunbury have dealt with all manner of makes/models, and are highly recommended by Auscruise themselves.
Will let you all know how it goes
