Sound depends, device crashes and then for days no longer bootable

*** Update ***
Meanwhile, the unit has been repaired with costs and now works.
The trouble is that the whole thing was a water damage, which resulted in the withdrawal of the warranty / goodwill. Water damage in a waterproof device .. Do you notice something? ;-)
While the device does not crash now, but it can not compete with the navigation via waterproof cell phone.
The Bluetooth comes with a connected mobile phone and the headset is connected, unfortunately, often confused, so I can not always connect with the headset the phone.
Partly senseless road layout leads to the conclusion that I would continue to prefer a waterproof mobile phone.
Preposterous means that in the countryside boring highways are preferred, while in town partly totally lame back roads are preferred to quickly navigable major roads.

*** Update *** End
Hello There!
Unfortunately, I can the largely positive assessments absolutely not connect.
My device is an absolute disaster.
Unfortunately, I have used the unit here on Amazon and purchased with expired Garatie, a big mistake I have unfortunately noticed only after the Return Period, there was no motorcycle season.

Tonabsturz
I, and many other users have the problem that the sound abstüzt häuftig. It cracks like a radio with station search and then the sound is gone. Then, when I make the mistake and go into the volume settings, smears from the Navi. Only after battery removal, hard reset and a lot of patience (in Motorradurlaub once even 3 days) I can then start it again.
This problem is widespread. Look after the Garminforum:

no winding route
although for motorcyclists probably most meaningful benefit of Navis is, this option is completely missing in Garmin. Many of my friends have a Tomtom, which has led us to the most fantastic routes along while my Wuscher-Garmin has picked here only main roads out.

Many Errors
In a motorcycle tour with over 100 people I've talked with many Garmin-users. Almost everyone knew to report crashes and quirks that could be resolved only partially by much patching, updates and Tricks times. With me everything helped nix.

way too expensive
There are of Tomtom significantly stabiliere and cheaper devices.
Generally, it must be asked whether it is not sensible to bring a waterproof smartphone like the Galaxy S4 Active, do spend so much money on a pure Navi.

Conclusion: Stay away, you buy a tom, or even better a waterproof smartphone. I hope that I find a masoschistischen Ebayer who buys the thing for a few euros me.
