So, I've been using the Nav V for some 4 years now. The mapping software has become so bloated that it needs to be on an SD card. This along with music and routes slows the device down so much that the refresh rate doesn't keep up with the map, so in town you're lost. My unit regularly reboots in use. The routing algorithms are crazy too. I can't remember how many times we've been sent up a single-track dirt road for no apparent reason. My old Tom-Tom was a better and more intuitive device. Shame as the Navigator promises so much but fails to deliver.
Garmin don't give a shit! They have not provided enough memory to cope with their bloated maps and need to allow minimal upgrades for older units. I dare say the VI will not be future proofed either.
They have offered me a replacement at a cost of over £120, for a refurbished unit. It’s a worry when my own V is in mint condition (apart from being worse than useless at times). Not funny when you have a group following you!!!
A recent trip to the Pyrenees was a disaster, as even although I had installed whole Europe map, only North Europe was visible? Another trip this year to Dresden and Prague I had no mapping when in towns - which was fun. I asked Garmin to upgrade me (and I'd pay the difference) but they are not in the least bit interested in customer loyalty. Be the last Garmin I use, and this may influence me not to buy another BMW. BMW take note!
The apps for route planning are also abysmal, in no way user friendly.
You have the most amazing patience to put up with the Garmin for so long.
You should continue to enjoy your BMW motorcycle but move back to a TomTom. I note that in the Consumer Which? tests the TomTom usually comes out just ahead of the Garmin as a car SatNav, so they are excellent units.
Please accept that there are many others (including myself) who are happy with their Garmins and the Basecamp route planning software.
