Is this one of those "technology breeds technological need" things?
Do you need the speed camera database now because you are sitting on the bike with your eyes glued to the SatNav?
That's a bit unnecessary, isn't it? Perhaps it is because when he goes through five different countries in a week, it can get a bit of a pain to remember just how close the street lights need to be together in this latest land before the lower local speed limit is enforced. There are also times on the bike when I am, well, let's say "pressing on", and prefer to spend 100% of my time looking at the road, with none of it looking down at the speedometer. A beep to point out when I am approaching a camera is a useful extra piece of information. You could argue that "tight bend" or "adverse camber" signs are equally unnecessary to some apocryphal perfect rider, but most of the rest of us are happy to take in whatever piece of useful extra information we can get. The speed camera database gives you one extra thing to help you choose the appropriate speed for any given time, that's all.
I can never really understand these comments that seem to deride people's use of new technology. Only a few years back, I had exactly the same sort of thing when first fitting a GPS to the bike. People would say "Do you really not know how to read a map", which is a similarly unnecessary way to view it. I can read maps pretty well, but like to have a GPS on the bike. It has proved invaluable when I wanted to head up an interesting looking trail, for example, and just keep riding until I was bored. Much quicker to simply pick up the GPS instructions again when it was time to head on to the next stop than to get a map out in the rain and dark and start working out which mountain I was on top of.
Now, however, to return to the question of which GPS...
I have just ordered a Nuvi 255 from Halfords for £110, to replace my Miomap. The Miomap is still OK, but the maps are a bit out of date, and I fancied a change. It does not allow route planning, but lets you put in enough waypoints that I never found it to be an issue. If I want to go on a particular road, I'll stick in a waypoint along it, and that always seems sufficient. I like the very small size of the unit, and the very few touches needed to get me to the closest petrol station. The more expensive units definitely do have many more features, but I personally find that the entry-level systems do all that I need. I prefer to keep my phone and music separate from my GPS (an iPhone in an inside pocket, with the micrphone inside my helmet works very wekk, and I have a Belkin sportCommand control that sits on my left arm for changing tracks), and so want only something that will direct me via the route that I choose to my final destination.
