We have the SR1. Its basically identical. Wierd: our display unit is mounted the same way as yours.

Iv been thinking about getting laser diffuser unit also. I personally think that the passport sr1/srx, while doesnt give direction, has much better performance.
-Range is fantastic
-Virtually no fasle signals
-Iv gotten hit by laser at least 6-7 times while speeding (me>95mph, i was>100 couple times), Iv yet to get pulled over (btw, im knockin on wood as i write this).
-K band is just as good.
Laser detection imho is unrivaled. My friend has valentine/stealth in his X. He agrees this is better.
