Summary: I received in early March. It worked fine for they few times I was able to get out on my bike due to weather. The GPS is hardwired into electrical system. Went to use today and GPS will not fire up. (Fuses were checked, plugged into cigarette lighter and light on cord came on, but not GPS and have plug into computer and not working) Cannot return through Amazon as they only give a month. Have to deal with Garmin.
Summary: I've had a Zumo 550 for years. The 550 is "friendlier" when it comes to phone interface. The 550 is MUCH EASIER to see the screen in bright daylight conditions. I put my 390 on "Night" screen not long after I got it as it was nearly impossible to read in direct -or- bright sunlight. The "screen viewability" of the 390 -vs- the 550 is a giant step BACKWARDS for Garmin !
Summary: The unit is okay for me as I use the mini plug to plug into my motorcycle. For me the problem is that the unit documentation states that it is sun light readable, well that's not true it's better than the Nuvi line but the old Quest2 is truely a sun light readable if only they wouldn't mess around with a good thing and mess it up.
Summary: A very nice unit as you'd expect for the price. The fitting instructions are confusing, and nothing is identified: hunt for your washers and spacers, they are in there, just not packaged with base plate. The software (downloadable separately and free) is a complete load of birds mess.
Summary: I would like to have given it five stars as its an excellent SAT NAV and does exactly what I wanted it to do on my motorcycle with the added bonus of having a car kit supplied as well. However... The big problem is Switzerland, for some reason it will not accept fairly main roads preferring to route you hundreds of kilometres instead of a very short distance. Try the Furka Pass to Interlaken for example, a 40 mile journey is shown as several hundred!
Summary: Incredibly expensive, hard to use, not particularly advanced software & PC software (BaseCamp) truly awful compared with Google Maps. Still, there isn't much choice for motorcyclists, at least the outside of the unit is compact & sleek, unlike the mini suitcase that is the TomTom Rider... Sept 2012:-See my further comment below.
Summary: We have and continue to use a Garmin 550 on my wife's bike. I expected the new model for my bike to be even better, it's not, while certain features are better and the touch screen is lighter to use but the very cheap mounting system does not lock the unit in place, a small screw holds the 550, it can't be used with a phone in a vehicle and again the mounting is dreadful and It did not come with a carrying bag.
Summary: Das war mein großes Problem. Dann befindet es sich im Demomodus. Hat sich bei mir selber aktiviert, über Nacht beim Laden. Um den wieder zu deaktivieren: Auf der Haupseite auf "Lautstärke" tippen, im Lautstärke-Menü die rechte obere Ecke gedrückt halten bis die "Diagnostic Page" erscheint.
Summary: Im Vergleich zu allen Navis die ich schon getestet habe ist das Zumo 390LM immer noch das Beste. Leider haben sich auch hier hie und da Kartenfehler eingeschlichen. Die Navigation klappt leider nicht immer ganz Reibungslos. In der Schweiz wurde ich schon auf nen Abzweig geschickt bei dem ich ich mich von der Beschilderung her wunderte warum ich woanders hingelotst werde um dann hundert Meter weiter zum wenden aufgefordert zu werden. Kein Drama aber recht nervig.
