I am not able to make it work with Garmin fit.  It cannot find the sensors.  I install fresh batteries but they don't work.

there is no light coming from the sensors, even after pedaling long distances.  Very disappointed.

My Samsung Note 3 with Garmin fit is able to connect to the Heart sensor from garmin.  I know it works, but this little buggers don't work.

UPDATE.
I spoke with Garmin support and they said this sensor don't work with Garmin fit. They work only with bike computers or wearables such as fenix.

It should be clear on the description the compatibility issues and check on garmin website.  This will make it easier for the consumer.

The item is less than a month old and it keeps responding that maps are unavailable. I've tried entering addresses, points of interest, etc., but I get the same result. Additionally, no manual or any directions came with the item. My older Garmin works much better than this new one I purchased for my dad. I wish I would not have purchased a different GPS for him. I wasted money on this one!

Bought this card and could not get to install on Windows 2000.  Called tech support and they emailed me an updated driver but it did not correct the problem.  The computer recognizes the card but there is the dreaded yellow exclamation point by the device with a Code 31 error.  After spending a few hours, I threw in the towel.  I think I'll try a DLink or Orinoco.

I bought this base model and the Garmin website does not support this model for downloading any maps.  Very unprofessional.  Why sell units that you don't support?!

This was not easily programmed and was impossible to save locations for future use.  I tried copying data from my old Garmin to this, however, it would not recognize the locations.  You had to physically sane the location you were in once you got there, instead of saving it before you started your journey.  I would not recommend this unit.

It was a factory refurbished and the computer hookup cord did not fit the inlet to the unit. The twelve volt car hookup fits and the Unit workd OK but I cannot register the unit or get updates because Garmin does not recognise the unit when I use a computer hookup that fits into the unit.

I once owned an expensive Garmin that cost several hundred dollars and was reasonably satisfied with it. I gave it away when I got my iPhone 4 since I could navigate using it. Well over time I have become annoyed by the weak GPS performance of my iPhone and wished it had the accuracy of my old Garmin. So with the great reviews for the Garmin Nuvi 50 and the low price I ordered one and received it today. The following issues are the reason for my returning it:

  I entered the name of a very popular pizza place and the hour glass spun forever with no result. It clearly would
  have killed the battery without ever timing out. No big deal, they can't have every place in their DB.

  Even after updating the maps when I entered the actual address, 914 Main Street, it located 914 W Main Street
  which is a completely different address! There is no way to reject the mistake and get it to show the correct
  address.

  When I want to view a route it is very difficult / impossible to page to see it as it keeps showing addresses and
  it displays 2 choices GO and Save. How about Neither! I don't want to Go or Save I want it to stop offering
  that! I don't see anywhere to turn that mess off.

  The final straw was after the initial GPS synch it is supposed to be very accurate, but after turning it off and
  on it showed 75% signal strength but it located me about 1/4 mile from where I was! Accuracy was the whole
  reason for getting a dedicated GPS device again in the first place!

I wanted to like the Nuvi 50 but I will take navigating with my iPhone over this mess any day!

Works fine, although doesnt work with de Training center. But you can use the Garmin Express web app. Its enough for me.

The code worked once and I locked my bike.. Was never able to open it again with the same code. Not recommending  anymore.. Looks well built but I think it just doest solve the purpose of locking AND unlocking..

See above comment.  Before purchasing, I should have been advised of the computer requirements necessary to register the GPS and to get  the maps installed!

Installed it in a Garmin 2599lmt. I thought that I would need it for my 1st update. I did not. So, while I did not write anything to it, it does test as
genuine, and I have it for "if and when" I need it.

Purchase of a Garmin GPS (the Nvi 2475LT) lead inexorably to a two-day nightmare.  I strongly urge you:  if you own a Mac, don't purchase a Garmin.  You'll never be able to update your maps.  Here is my story.

I had already owned a Nvi 780 for a few years, but I never registered it or updated it because of the difficulty I had with the Garmin Website.  Lately, as I was about to take a European trip, I decided to try again to register the unit, purchase an updated US map, and a European map.  I then learned that I would need to buy and install an SD card to download maps on this older unit.  With the cost of the card and the maps (expensive), I decided it would be more cost effective to purchase a new Garmin with US and European maps already installed.

When the Nvi 2475 arrived, I registered it and tried to get the one-time free map upgrade--something you must do because the units are sent out with old, outdated maps.  To my surprise, I could not update the maps without purchasing and installing an SD card on the new GPS, advertised to have both US and European maps installed.  With my trip looming, I went out and purchased an SD card, installed it, and logged into the Garmin Website.  That is when the nightmare began.

The first day I was on the phone with tech support from 9:00 AM until 5:00 PM, which included remote sessions during which the technicians had remote access to my computers.  (They had me running up and down stairs attempting to install the maps on two different computers that I have home, thinking the problem was Computer No. 1.)  The result of Day 1 was a failure to load the maps on either home computer and a disruption of my home Internet service.  That evening I had to get in touch with my Internet provider to troubleshoot the mess with which the technicians left me.

After being told that the problems must be my two Macintosh computers at home, I tried from my office on Day 2.  Again, I was on the phone with tech support, this time from 11:00 AM until 4:00 PM, again with multi-hour remote sessions. At 4:00 o'clock the technician had me read to him several bits of information from the Garmin GPS itself and then told me we were successful downloading the updated maps and I that was all set.  As soon as he disconnected from my office computer and we hung up the phone, I tried to enter an address on the Nvi.  I got an error message:  "No maps installed."

So after two days with Garmin support services on three computers at two addresses, I was left with no GPS and no home Internet service.  Great job!

Save yourself a great deal of aggravation:  Don't buy a Garmin!

DO NOT BUY THE RM 730. You just as well flush your $400 down the toilet..I have the 720 and 730. Now I rely on my Garmin 770,it has yet to lock up with error messages. Thats right... Add up all 3 units..almost a $1000...RM tech support will tell you anything...because they don't have a answer for all the software glitches. Garmin so far has been dependable. RM better fix the problems or no one will trust that GPS brand anymore.

Don't know if this is common to this or other Garmin products, but here's my story. Turned on the garmin to input address while riding on the airport car rental shuttle (battery was charged). I get to Hertz rental - FORD ESCAPE, screen says "searching for satellite." Start the car, plug the garmin in, and the screen suddenly goes BLACK. My iphone is still synced with the garmin so I know it's on.

Tried it again in a different rental, then in two cars at home. Still black screen and no functionality!

Totally puzzled and annoyed. Went to the Garmin website to register my frustration (and unit). Found the Garmin packaging, took out the computer cable and plugged in the USB to the computer and the other end in to the power port on the back of the Garmin.

Voila! Screen works again.

Downloaded the updates while I was at it, and hoping will not have a recurrence. Cautiously optimistic which is why the 2 stars.

Purchased the Garmin nuvi 44 on September 24th, 2013 but by November 3, 2013 it had stopped worKing (& Amazon indicated it would not accept a return since the returm window for this device had expired & then Garmin said I had to return to where I purchased it - a sure Catch 22). The unit basically freezes on the logo screen or when trying to reload maps.  Then the unit just shuts down.  Tried to update the drivers & installed new software several times as recommened on the Garmin site  as a "fix" for these problems but my  Nuvi 44 still doesn't work.  Since I've already spent hours trying to do updates, install new drivers & upload map updates several times, I've decided to just junk the Nuvi 44 and buy another GPS from a different manufacturer. .

Was happy the item is able to be manually programed and with the computer. Was disappointed that when I went to update it's maps was told device storage was 97% full. Called them and was told they had no technical dept. To call Garmin about it. Was very pleased Garmin solved my problem. They are sending me a sd card to take care of the extra memory needed.
