Map/screen refresh lagging
I have opened a ticket with Garmin but has anyone else had issue with the map or screen refresh lagging when traveling at speeds above 50-60Kph? Blanks fully or partially with only background colors, then some map details then the complete map. Repeat 10-20 seconds later. Like an old computer with the graphics card struggling to display an HD video.
I have the 700i, I've noticed this using City Navigator or Topoactive. Separate profiles and only the applicable map is active (no overlay of multiple maps), GPS powered on the Garmin rugged mount, map speed at fast or normal makes no difference. GPS mounted on a motorbike so it has no obstruction to the open sky.
This would happen sometime on my old Montana 600 but only when zoomed into a very high detail map. otherwise it was flawless. The 700 right now is horrible.

I also noticed this today on some "German Bundestraße". Map just freezed for 5-10 seconds and then suddenly continued refreshing. Firmware 8.20.

Re: Map/screen refresh lagging
Same problem here. I tested it on a KTM Enduro R and a Honda CB650R, but with both bikes the same problem.
The map disappeared for a second and than came up again. The same as in the video above. I noticed that flashing came up above 5000rpm.
Sometimes only a white screen for a 1-2 seconds.
Firmware 8.40 and it doesnt matter if the map directly is on the Montana or micro-SD. No external powersupply.
Tried different maps but same problem.

Re: Map/screen refresh lagging
Garmin have reported back and are apparently doing tests on their end and asking if I could do some more.
I have also reported to Garmin that 2 other members of our groupe also have the 700i and noticed the same issue.

I will be isolating the contacts on the GPS and mount and running it off battery to do more test as requested by Garmin. I will post update once done.

Hello Ivan,
Thank you for your patience while we investigate your case! We are still testing some Montana 700i's on our end and we had a few questions. We know this would not be safe to try on the bike, but if you were use the device without the mount (in the car perhaps) does the screen still refresh rapidly like it does on your bike? They are wanting to see if maybe it is a connection issue with the mount. They also wanted to know if this was on all the screens and just not the map?
Thank you for choosing Garmin,

I tested it in a car (without bracked) and the screen was normal. On my motorcycle is use a Rammount without cable, so the problem cannot be the connection.

Re: Map/screen refresh lagging
It seems to look like some sort of frequency / vibration issue.
Here: https://www.naviboard.de/thread/66137-k ... post531877 a user says, that this issue happens by about 5000 rpm on his bike, even without any external power.

Re: Map/screen refresh lagging
This evening i did a small test. First in the Rammount bracket without external power, the screen was flashing at 5000rpm. After that i used it as a handheld and nothing happened, so no flashing. It was only a small test, but it seems to be the problem is the vibration/bracked so far.
In a few days when the rain is gone i will test it again. I will also test it with another motorcycle.
