Garmin Zumo 390LM GPS
Unacceptable quality of power connector
GPS unit itself works well, and I have no issue with screen visibility in bright sunlight when back-lighting is set to 100%. However here we come to a problem!. The power connector installed on the base is of very poor design, and although its two small connector pins are apparently gold plated, they are IMHO too small, and the springs keeping them out are of insufficient strength. Result is that already on the first day of riding, GPS started reporting loss of external power, and tried to switch itself off every few minutes. This results in several potentially dangerous situations: Firstly when it does that the back-lighting automatically goes down to 40%, and then you really do not see the screen, and secondly you are forced to fiddle with the GPS every few minutes instead of watching the road. Absolutely unacceptable for a 600$ unit!

Unreadable in daylight
I have loved Garmin from the get-go, so when I needed a new GPS, I went with the 390LM. I tend to ride long distances and love the off-the-beaten-path routes. So, I mounted the Garmin, hooked it into the electrical system, and took off for a cross-country trek. It turns out I could only see the screen while riding in the shade. Next issue came only a few hours into my ride when the unit decided the battery was low and shut down - even though I had the cradle connected to the bike. I rode 8,282 miles in five weeks and used the Garmin for only about 500 of those miles.

Zumo 390LM Better Than Expected
The Garmin Zumo 390LM right out of the box does indeed have a few oddities but the good news is that updating the unit to firmware version 6.17.07 (or later), fixes a number of bugs that were found on stock 390’s including the annoying beep-issue that many have complained about in their reviews.
The 390LM (LM=lifetime map upgrades) can be USB connected to your home computer and fully upgraded on-line by Garmin in about an hour. The free GarminExpress program will update Firmware, Software, Traffic, Bluetooth, Maps, and register the 390 in one session.
As for the complaints about not being able to use the live Traffic function in the motorcycle cradle; that was done in order to meet the strict waterproof ratings that are advertised in motorcycle mode.
With a 17mm G-to-B ball adapter and a GMT traffic receiver cable (both sold separately), you can use the automobile cradle & GMT traffic cable on your bike and get live Traffic data on the Zumo 390LM while you ride. Be aware that doing this will reduce your device from being waterproof to merely water resistant.
Both the automobile and the motorcycle mounts are included with the Zumo 390LM so you can try them both and decide what you feel is best (safest) for your type of riding.

I purchased this to upgrade my Zumo 450. It really is not much of an upgrade. Yes, it is faster. It has some bell;s & whistles that are only useful to a select few people. The screen is bigger, which should be a good thing, but, it turns out that, contrary to the manufacturers claim, the screen is virtually unreadable in direct sunlight even at the highest brightness setting. I connected a bluetooth headset to the GPS to at least be able to hear spoken directions. The unit defaults to searching for an address in an area that is not even relevant to where you are. Satellite acquisition is fairly fast.Disappointment overall however.

If you want to throw way good money, buy the 390! It sucks
First let me say that I love Garmin GPSs. I have owned about 8 of them and I only buy Garmin! With that said, the 390 sucks!
I wish I have bought the 600 series from Revzilla, but no… I want the newest and best…. 390LM is lacking in so many areas that is not funny. Software lack of many basic functions that my sumo 550 had.
Hardware…. Unless you are using the Car cable charger, the Traffic function does not work, because it is its antenna… Well great job Garmin, so it is supposed to be a motorcycle GPS with motorcycle bracket…. Another useless function.
I am a little disappointed with Revizilla also, because when I called trying to trade this GPS, they would not do it. Unlike anything else they sell.. If you open the box of GPS they will not take it back! So much for the great Revzilla Cost. Service.
So, I figure I try to help the next guy since I got screwed out $700, mostly from Garmin

always find your way home.
Due to the weather this winter I have not had a lot of oppertunity to use . However I have used and it works as advertised. A lot of information right in front you. I paired it to my Scala radio and receive all my direction with no problem. Everything you need is in the box. The mount is simple amd functional. So go ahead get lost, enjoy the ride and when your done just hit the home button.

The Zumo 390Lm has a great screen and the exceptional Garmin features. However, the programers forgot to add the TOOL to Adjust the Volume applications to the device on the Volume Screen. Though listed in both the Garmin Quick Reference & Owners Manuals this feature was left off the 390LM. What does this mean. Your Zumo 390LM will beep every time you press it unless you place it on Mute. If you use the Bluetooth feature this will interupt all other attached Bluetooth devices again unless the device is muted. The Navigation Voice Blares out at you even on the lowest volume settings. Very Rider unfriendly device.
Per Garmin Automotive Support they have no intention of updating this device & plan to change the Manuals.
