I am disappointed with my recent upgrade to the zumo 590, having had several Garmin devices over the years. I appreciate that Garmin has to modernise its products to remain competitive, but including features which are a hindrance and omitting good navigation features from earlier devices doesn't seem to be progress.
On start-up, the software on my 590 intermittently cycles through the route calculation 2 or 3 times on routes that have been planned and uploaded from my computer. My previous devices have never done this. On first use, the spoken directions were deafeningly loud in my bluetooth headset, which I adjusted. Upon subsequent use I could barely hear instructions no matter what I did with the 590 and latterly the spoken directions became non-existent, so given the other issues with the unit, I have given up trying to fathom the problem or the answer. The volume icon on-screen seems pointless, since it only produces an instruction to adjust the headset volume control. Spoken directions are very important particularly when riding at speed, they help me to know when I’m approaching a junction or road where I need to re-position myself. Having to depend solely upon a screen when the audio won't function and frequently check it for direction of up-coming junctions can be dangerous especially in fast moving traffic.
The unit will not run a bespoke route unless it is set in ‘curvy roads’ mode, whereas the zumo 660 predecessor ran bespoke routes whether set to ‘fastest’ or ‘shortest’ modes, and unless the ‘curvy roads’ feature is deselected to be able to reach a single destination point directly, the unit directs you everywhere except where you want to go. It seems a retrograde step that the 590 will not run a bespoke route in its 'fastest' or 'shortest' route settings.
Recently plotting a route directly on the 590 incorporating various waypoints and having to use it in ‘curvy roads’ mode in order to run the route, produced endless confusing deviations and instructions to turn around, and had I been using the 590 where I was unfamiliar with the general direction, roads numbers etc, I would have been directed endlessly out of my way.
The 590 also produces incessant alerts, to the point that they become distracting and they're ignored. I don’t want to receive alerts for every restaurant and petrol station on route, but I do want safety camera alerts, but as these are all grouped within one setting, I seemingly can’t have one turned on without the others. I’m disappointed with this feature, especially having purchased the camera alerts software upgrade.
The cradle is unique to the 590 although the 18 pin rear connector looks the same (590 v 660). I don't know why cradles cannot be standardised so that devices can be interchanged (or upgraded) more easily, swapping the cradle mounting is costly in garage charges, which I've now done twice on my bike, having reverted to the 660.
It seems that Garmin has taken a good device (zumo 660) and made it greatly more complicated but has not retained its good features. My purpose in buying a motorcycle sat-nav is to be able to plan and ride bespoke routes and receive reliable audible directions and relevant alerts. My 590 fails to do this, therefore I have reverted to the 660 and am disappointed to have wasted money on an expensive product that does not give me the essential navigation information that I have come to expect.
Unfortunately Garmin customer services has not been able to provide me with assistance to overcome any of these issues.
