Scruit Posted May 20, 2008 Share Posted May 20, 2008 When I put my c340 in my '05 LGT limited (standard suction cup mount) I get almost no satellite reception - and even on clear days without a cloud in the sky I get only about 50% coverage. My wife's car ('01 Outback) has no problems with the same GPS device (not the same make/model - the exact same unit). Anyone else here has problems with GPS reception inside their car? I'm thinking I need an antenna (which would be a PITA for hiding the device...) BTW, I have a trunklip mounted GPS antenna for my dashcam and it gets great recpeption - even inside the garage with the door closed! Link to comment Share on other sites More sharing options...
iyalla Posted May 20, 2008 Share Posted May 20, 2008 I bet your dashcam GPS is interfering with the Garmin GPS. Link to comment Share on other sites More sharing options...
cmc032 Posted May 20, 2008 Share Posted May 20, 2008 that is so ridiculous. But yeah .. what he said Link to comment Share on other sites More sharing options...
Scruit Posted May 20, 2008 Author Share Posted May 20, 2008 The dashcam is wired - not wireless. It's not in the GPS's line of sight. If it was the dashcam then the GPS woudl work when the car/dashcam is off. We'll see. Link to comment Share on other sites More sharing options...
rouar Posted May 21, 2008 Share Posted May 21, 2008 Try moving it to various locations on your dashboard and see what happens. In my old car, the Bose head unit interfered with reception if I had my Garmin C320 GPS in the center of the dashboard. I could use my GPS or listen to the radio, but not both. Moving the GPS to the A-pillar resolved the issue. I prefer it in that location anyway, it is much less visually distracting for me. Link to comment Share on other sites More sharing options...
LongHiway Posted May 21, 2008 Share Posted May 21, 2008 If it helps, I have an '05 and use a Magellan protable GPS. Never had a reception problem. Uh, you waiting long enough to get the signals triangulated? That can sometimes take 5 or so minutes. Link to comment Share on other sites More sharing options...
Scruit Posted May 21, 2008 Author Share Posted May 21, 2008 Tried it at the A-pillar - no difference. Clear blue sky today, kept getting signal then losing it again. I ordered an external antenna for $15 - that'll fix the problem. Link to comment Share on other sites More sharing options...
LongHiway Posted May 21, 2008 Share Posted May 21, 2008 You don't have satellite radio do you? Sure seems like something is causing interference Link to comment Share on other sites More sharing options...
Scruit Posted May 21, 2008 Author Share Posted May 21, 2008 No sat radio. If I open the sunroof and hold the GPS unit higher than roof level it works fine. Link to comment Share on other sites More sharing options...
Kargurra Posted May 21, 2008 Share Posted May 21, 2008 How 'bout window tint? Metallic tints will interfere with most radio wave reception.

Vetterin Posted May 21, 2008 Share Posted May 21, 2008 I have the cheaper C320 and have had no problems over the past two years. Are you sure you have your GPS mode (on the system screen) set to normal and not WAAS? Link to comment Share on other sites More sharing options...
Scruit Posted May 21, 2008 Author Share Posted May 21, 2008 I have it set to WAAS. When I set it to normal mode the accuracy is too low - it sometimes thinks I'm on a parallel street. Works 100% in my wife's car. Just not mine. Go figure. Link to comment Share on other sites More sharing options...

Oh, you've used springs to lower your car and the now the signal doesn't reach. Back to stock. Older Subies had a stick antenna, wierd that hidden antenna seems affects your GPS. Based on the other post, gotta feeling it's the antenna on your GPS. Link to comment Share on other sites More sharing options...
