I also use copilot, I have the full EU version and have used it for a motorcycle trip across France Belgium Germany and Austria and in my van further onto Hungary Romania & Bulgaria.
I'm intending to use it again this year in the Berlingo for another trip to Bulgaria. A function I find valuable is that Copilot will report the local speed limits in MPH the same as my UK speedo and warn me if I go over, which is very useful in Romania where the police regard speeding motorists as their personal cash dispenser !
Google maps is also very good and free , you can also download routes on WiFi before you set off if data is a issue like abroad or if your on PAYG mobile.
I find the scorche magnetic car mounts superb for secure easy mounting of the phone.
I suppose it depends on how much you drive, as to how much you should spend on a sat nav. I drive over 75,000 miles a year as a same day courier, and I use a Tom Tom Go Live 1005 which has live traffic info fed to it every 3 minutes. This is the second 1005 that I've owned, and it has literally saved me from hours of being stuck in traffic jams, as it automatically steers me around any major holdups. The traffic subscription is £38 per year. Good though it is, I still occasionally, have to use "Google Maps" on my phone to be directed to newly built roads, not on my Tom Tom's map.
I have used Garmin, Navigon, and CoPilot sat navs in the past, and none were anywhere as good as my Tom Tom. The only good thing about the Garmin which I keep in the van as a spare, is that, you can put in up to 20 drops and it will optimise a route for doing those drops.
Jim, maybe try waze as a back up as it is a google product so new roads are all up to date etc. It also has the added benefit of speed camera locations and users can upload where mobile cameras are for other users to see - again it will give you a warning to let you know there is one.
