I've read a number of posts discussing the sensitivity of the gps chip in the GX65 and 9500ix. It seems the observation was that the GPS in the detectors would not pick up a signal unless the detectors had a clear view of the sky. If you read the technical information about the Belscort GPS detectors you will find that the GPS chip that is used in the detectors is the SIRFStar III chip. As an avid follower of standalone GPS units, I recognized from research that this was one of the best GPS chips out there. Many major GPS manufacturers used this chip in their product and touted the use of this chip on their packaging. The benefits of using this chip was that it was supposed to aquire a gps lock quickly and then would hold onto the signal better than other GPS chips even in inclement weather and when driving in areas with tall buildings that would normally disrupt the signal of lesser gps chips. Earlier Garmin Nuvis used this chip. Garmin currently does not disclose which chipset is used in its GPS units. I have had a number of GPS units from Garmin and Magellan that used this chipset and the units were all able to obtain a gps lock and maintain a signal when not mounted on the windshield. I have been able to use the gps units even when the units were placed in the seat and center console.
Why all of this discussion? Beltronics indicated to me that it is not recommended that I mount my GX65 on the visor or in a visor pouch because the detector would not get a GPS signal. I have mounted the detector high, I have mounted the detector on a visor, I have placed the detector in the seat and center console cupholder and each time it has obtained a quick gps lock and maintained the lock without dropping a signal. I don't own a visor pouch as I held off purchasing one based on Belscorts warning. Now radarbusters are out of them. I had an old soft camera case that the detector fit inside. I cut portions out of the detector so that I could get the detector onto the visor mount and get the power cord into the side. I powered up the detector and mounted it high on the visor. Guess what? I got a GPS lock and maintained the lock without dropping a signal. It's ironic that the only times I have had signal drop issues were when the GPS was not mounted high and was mounted in the middle of the windshield. Your results may vary, but I have had success getting a signal anywhere the detector is mounted. Wish now that I had gotten the good deal on radarbusters before they discontinued carrying the visor holder.
