I'd be interested to hear how the Garmin performs Bowfer. As you know it was my other option besides the Snooper.
It's very kind of you to go and buy both just to do me a product review!
Finally had the opportunity to use the Garmin.
Compared with the Snooper, it's a mixed bag.
First and foremost, the Garmin has Euro mapping, which the Snooper didn't.
Moving onto other things;
I prefer the map display of the Snooper, no question.
More colourful, with scrolling clouds etc.
Much nicer to look at, with the Garmin's looking a bit bare in comparison.
Then again, the fact you can change the vehicle on the Garmin display, to anything from a tank to a slice of pizza, is quite entertaining.
Phone function, the Garmin wins hands down.
Once connected by bluetooth, it transfers your phonebook to the display, which the Snooper never did.
Garmin's microphone appears to be better than the Snooper too, with less of the "what?, you're breaking up" annoyances.
I would say Snooper wins the speed camera function too.
Its alerts are bigger and brighter, and more easily cancelled.
Once you get a speed camera alert on the Snooper, you can just cancel it by pressing the screen.
If you can do that on the Garmin, I can't find out how.
Which means you get annoying warnings 'binging' at you all the time you're in the speed camera area, even if you know it's there.
One other pretty major gripe with the Garmin is that once you programme in a route, the speed display changes to 'time of arrival'.
You cannot change this.
You can get speed displayed, by switching to another screen, but you can't have map and speed.
Conversely, if you don't have a route programmed (so it's just showing an 'aimless' map) you can get the speed displayed.
Going by Garmin's FAQ page, this is a common complaint from owners.
Loads would like to choose between time of arrival or speed, not have it forced upon them.
To sum up, I would say the Snooper wins the map display and speed camera alert functions.
The Garmin wins for European use and phone functions, and the fact Brodit do swivel mounts for it.
There's a good review here too

Oh, I've remembered to PIN-lock the Garmin too, so some some thieving scrote can't use it.
