I got my STI yesterday from Beltronics. It is version A2M8. They shipped it the same day I ordered and it arrived two days later. I was waiting to order from Roy but I am going on a trip in a couple of days and I didn't want to be naked.
I installed it using the supplied windshield mount. This seems to be a good method for a C6 Corvette. The suction cups can be put behind the tint strip and then the business end of the RD has a clear shot through the windshield. The rear facing laser sensor may or may not work because the horizontal cross section of the rear hatch is very small. Looking in the rear view mirror about covers it all.
The electrical connection was hard wired to the plug in the back of the rear view mirror which contains among other things a ignition switched +12v and a ground. The connection was made by soldering d-sub pins to the wires supplied with the RD after cutting off a suitable length with connector from the supplied direct wire harness. For anyone else going this route the two middle wires in the connector are the +12V (red) and ground (green). The pins can then be jammed into the crimped metal in the back of the rear view mirror connector where the original wires are connected. The unit draws about .25-3 amps when just sitting there looking for a signal and about .4-.46 amps when powering up the audio and visual alerts..
I have put about 100 miles after installation but so far the only thing it has picked up are several K band signals from various stores. This was on autosense. On the way back I used the city mode in this area and it picked up nothing. I tried going by the places where the LEO's usually hang out but no one was around. Maybe there is a donut festival today I am unaware of. The laser sensor did respond to my Laser Pro Golf Range finder although I did not try to see haw far away it could be sensed.
When I finally come upon some real radar/laser traps I'll post my observations.
