I'm looking for a GPS radar detector which can be manually programmed by entering the exact GPS location.

I'm a happy Valentine One user and I never used GPS detector before. From the product descriptions I can see most of them are programmable and updatable via Web. But I'm not sure about the ability to enter the exact coordinates (or pinpointing the location on a map) manually via PC - is there such thing?

Please, recommend any good product for Europe.

Thanks in advance.
