BU-353 GPS receiver inconsistently locks on to satellites
I have a strange issue with my BU-353 GPS receiver inconsistently locking on to satellites. The GPS receiver is on top of my dash in clear view of open sky and there areno tall buildings around etc.
First off, a brief history: I've been using the BU-353 in my car PC for a few years now and it had been working fine. Then one day it just died and would no longer power on.
A couple weeks ago I purchased a new GPS receiver and everything worked fine the first time I installed it. However, after a couple days I noticed the GPS receiver would no longer lock on any satellites (the red light would not blink). I eventually exchanged the GPS receiver for a new one since it was within 30 days.
I received a new GPS receiver yesterday and again it worked fine the first time I installed it in my car (locked on to multiple satellites within 30 seconds). This morning when I got in my car I noticed the GPS receiver would not lock on to any satellites, no matter how many times I unplugged and plugged it back in.
Here is the strange thing; if I bring my laptop into my car and plug the GPS receiver into the laptop it works fine and locks on to satellites. It also works if I then unplug it from my laptop and back into my car PC, but only the first time. After a restart the GPS receiver no longer locks on to any satellites. I can also bring the GPS receiver indoors and use it on any of my computers and it still works fine even after restarting the computer.
Any ideas what could be causing this problem in my car PC?
