20 Most Recent Garmin Edge 305HR GPS Receiver Questions & Answers

I had the same problem, but it was unresolved using the above info. I finally went into the menu (Settings / System / Accessories) and selected Restart Scan. All is well now =)

Solution copied from Garmin



Pairing the Edge 305 and sensors
Once you have installed the Garmin Edge 305 and the cadence sensor they need to be paired. As they communicate wirelessly with each other the Edge needs to connect to each sensor before it can receive input from it.

The initial pairing needs to be done away from other wireless systems this allows the Edge to pick up the sensors it is supposed to be monitoring. This is a little like black magic, but it seems to work quite easily.

The cadence sensor has a small press contact which puts the sensor into pairing mode. The HRM just seemed to connect by itself.

Subsequent pairing is much faster as the Edge 305 seems to remember which sensors it is paired with. If you have problems or need to change one of the sensors then you can use a setup feature to either turn the sensor off or to re-pair it.

May not be linked to date of ride. Device has a limited memory, so you have to erase history when long rides, or frequent rides.
When memory is full, device is managing by erasing older data waypoints.

You may also activate intelligent recording of waypoints, that calculates waypoints record when direction or speed changes. This optimizes memory usage.

Maybe change the battery of your heart device. When going weak, the heart rate is not correct

http://www.mtbguru.com/ go there and all will be revealed my friend This is a common problem with 305/205... there is a battery connection in unit that thru use becomes strained(hence rough road shutdown) i followed the instructions in the blog and inserted a spacer in battery terminus and no more probs... good luck

Apperently my unit had some old data prior to my purchase, (amzon selling returned equipment I imagine)

Anyway, I did a hard reset, (turn the power on while holding the mode button down) Erases all history. I then paired up my accessories again, tested it in 1 second mode and smart recording mode. The hard reset seemed to work for me. My 305 edge is now downloading map and graph data to my PC. Hope this helps anyone with the same problem.

I have heard that the gold connector does not always connect with the +ive part of the battery. Others have bent the gold connector out slightly and the problem has been solved. Good luck.

You can configure the history hold duration. The user manual has simple explanation that you can browse at the link below

If communication error continues you can reinstall the driver

Good Luck

Your battery is dead. You'll need to return it to Garmin for repairs. Mine did the exact same thing. Functioned fine in the cradle - showed full battery - but shut off immediately upon removal. They know about the problem and shipped me a new unit for free.

Have a look on their web site; https://static.garmincdn.com/pumac/GPSMAP_78_OM_EN.pdf&vssid=collectionitem-web-desktophttps://static.garmincdn.com/pumac/GPSMAP_78_OM_EN.pdf

I suggest you try resetting the device by following the instructions in the owner's manual. If the issue persists, it may be due to an error in the map database. You can try reinstalling the maps to the memory card after unlocking them for your device. If you are still experiencing issues, please contact Garmin Product Support for further assistance .

By 'resetting' you mean it switches off, and because it is connected to power, it boots back up. Do you have a SD Card in it? I had trouble with a Nuvi 1350 with SD Card that had the whole USA Map on it, mine came with the Canada Map only. It would randomly turn off, so I decided to buy a Factory Refurbished Drive 50. I removed the SD Card and Reset the Nuvi and it worked perfectly after that. The Drive 50 was also a bit flaky, and resetting fixed that as well. You can back up your Favourites beforehand.

I recently purchased a Garmin GPSMAP 78s I had a lot of trouble calibrating the compass; I literally tried it hundreds of times without success. I also did a hard reset etc etc. Believe me I definitely tried everything possible but to no avail I did contact Garmin but they didn't have an answer straight away for the problem I have now sorted it as follows: Do each step VERY SLOWLY, MUCH slower than you think you should There are three steps to go through in calibrating the compass 1)Spinning the whole unit around flat 2)Flipping it over longitudinally and then 3) Flipping it over end to end. But remember do each step VERY slowly and go to the next step when prompted by the unit This solved my issue. I can now calibrate my compass 9 out of 10 attempts Hope that helps

To open the MTP settings on your Garmin Nuvi 50LM, you will need to access the device's menu. From the main menu, select the "Settings" option and then select the "System" option. From there, you should be able to access the MTP settings. If you are still unable to access the settings, you may need to contact the manufacturer for assistance.

You will need to go to the Garmin website on your computer or laptop and set up an account. I think the sign up is free. You will then need to connect your Garmin to the computer and update it that way.

Hi Earl, Sometime it could just be of aging. I have a 130, it was having similar problems, until i realized it was the screen not showing, but power on turning on. In your case, I probably probably try a hard factory reset as follows: To perform a master reset:

1. Turn off the device.
2. Press the PAGE, ENTER2, and POWER buttons simultaneously.
3. Release all buttons once the Do you really want to erase all user data? message appears.
4. Select Yes.

hope this helps! Kevin

It appears to be a known issue. You can try some Electrical Switch and Contact Cleaner in the first instance. This NOT WD40. https://www.google.com/search?q=Garmin+etrex+10+click+stick+problem ..
