Hello all, I know that there has been some discusion on Tracking devices before, but I'm considering having one installed in my SLK. My question is, does anyone have any experience of the Tracker or RAC Trackstar+ the Tracker seems slightly cheaper by about £30, but the RAC Trackstar+ has an option called Safespeed, which gives an audible warning when you are approaching a fixed speed camara. I'm wonderiing if it's worth spending slighly more for the RAC Trackstar+ and paying the extra £96 per year for Safespeed is this effective? I'm assuming that the camara details are updated and downloaded periodically, can't tell from the website. Anyone had experience with this? Thanks in advance.
