? Battery dead I've had a Garmin 405cx for about a year. It seems to have died. I have tried resetting it per other posts and in the past it worked. I've charged it in the clip....looks like it charging and then won't turn on. I have tried updating software, connecting it to my computer and resetting. In the past these thing worked. I really like this product by my 305 lasted three years. Can a battery die after a year...it won't turn on at all...any ideas. Given the price it should work more than a year.
I've had the 405CX for three weeks. After about 10 runs it has died. Reviewed problem on the web and found several threads with similar problems and results. Emailed Garmin and didn't hear anything back for more than 3 days. After calling Garmin and waiting for 35 minutes the rep told me withing 30 seconds I have to send the watch in to "swap it out". No response from Garmin online about this problem but this rep sure wasn't surprised. Are you kidding? ... return to Amazon. Not impressed with this over hyped product and lack of support from Garmin.
I've had the 405CX for a little less than a year but have been using it more frequently lately and the same thing has happened to me. Battery died and won't charge. I've done all the things that they suggest and the watch will not turn back on.
I was able to fix mine by 1.) cleaning the indents in the back of the watch is a scant amount of alcohol and q tips, 2.) doing a "hard reset", 3.) being very careful to make contact with the electrodes on the clip and balance the watch on something to make it stay in the correct position. I also emailed Garmin and had no reply. Great too...but crappy customer service.
Garmin Forerunner 405CX GPS Sport Watch with Heart Rate Monitor (Blue) After 1 year and 3 months, the Garmin 405CX will not turn on. Resets have worked in the past but now, the display says 100% charge complete but after I disconnect the clip, the screen goes blank. Updated software did not fix it. Very disappointed. Garmin's warranty is 12 months, issues started at 12 months. Hmmm, coincidence? :/
Mine does this all the time (acts like it's dead) - if you plug it into the charger does it come on? sometimes I have to put it on the charger - once it's come on hold down both buttons so it will do a reset and then let it charge. Sometimes you press the buttons enough and it will come on long enough to hold in both buttons and do a reset and it will go from 90% battery to 0%, but then it will let you charge it...
