Me too. I've been using it for several years now and it does just get better all the time, doesn't it ? Like all of these navigation devices they do take a bit of learning but I find MRA the easiest and most trouble free system yet.
It's not completely faultless though. I use it with a Garmin Zumo 396 and I've found that despite the instructions it will quite happily transfer Open Source or Tom Tom maps to your Garmin despite saying that it will only accept maps prepared on a HERE format.
If you do go for the Smartarse phone thing, download Garmin Smartphone Link and after a couple of tries it's dead easy to drop a route onto your Garmin Zumo just from your phone.
