For the last several weeks, since getting the replacement unit from Garmin, our 330 has been losing satellite signals with annoying frequency. There was no rhyme or reason and I ended up resetting it twice, of course losing all the data.
Well, today we were heading down to the Jersey shore to run the dogs and we figured out that the signal only gets lost when we insert a CD into the CD player. The 330 works perfectly with no tunes; works perfectly with just the radio and loses the sats almost immediately when a CD is played.
Anyone have any ideas? Other than don't play CDs :) Never seen anything this weird myself!
my 660 has been losing satelites lately. I found that if I extend the antenna all the way up it does not. Could there be solar flares? That will cause lots of troubles.
I've read that there was a massive solar flare recently that has cause havoc on alot of tracking systems.. they gave no time frame of when or how long that was to occur, but that may be what your experiencing.
I am really confused, the c340 is a separate system then the cd, correct? I dont see how it could interfer with the GPSr. It didn't happen before, correct? All electronic device (well, at least most) give out some sort of frequencies, but I still don't see how a CD player would interfer with the GPSr, but I guess you wouldn't post this topic if you figured out why...lol.
does not use the CD player...it was on a recent trip to Boston, where we took her car, that this issue really came to light. She had been saying she was having problems and, of course, when I went with her we did not have the CD on and the problems did not occur. When I put a CD in while taking a drive to Maine from Boston it did occur. We did extensive testing yesterday and it is clearly the CD player causing the interference. TOTAL WEIRDNESS is all I can say
BTW, it was happening before and we sent the unit back and it was replaced...at the time we did not realize the problem between the CD and the GPS...I was just hoping an engineering type could shed some light because I have no clue!
and the 330, without the CD player on, actually outperformed my 530 in terms of recalculating, etc. when the two were used side by side in my car. So, I am guessing that the solar flare was not the cause. In fact, I could duplicate the problem at will yesterday just by putting a CD in the player and watching the GPS lose sat connection...
Was the unit on battery power or plugged in?? It could be inproper grounding of the receptacle if it was plugged in. What vehicle make and model?? Was WAAS enabled at the time??
That CD issue is really weird, I cant wait until we figure it out! That power suggestion was a good thought, was it plugged in? Not sure if WAAS would do any thing.
I noticed that when I have my GPS plugged in to my laptop, WAAS is enabled and the TV is on, that every minute or so a buzzing noise occurs on the TV. Could be creating additional EMF (noise) and interferring with the transmission. Just a theory.
and the unit was plugged into the cigarette lighter. WAAS enabled and not, two different trials; the WAAS did not seem to make a difference. Good thoughts, thank you, I will try it with just battery power tonight!
A DC motor (like the drive on your CD player) emits a frequency and may be running in or spiking to the same band as your antenna.
Move the GPS further away from the CD player.
Try an external antenna.
Change your music - perhaps the GPS just doesn't like Country & Western.
ha ha ha, can you blame it not liking country and western?? Well, each to his own, I love trance, but I am sure that 95% of the ppl here wouldn't like it.
