Car Electronics Disturbs GPS Reception on the GO600
Fortunately, and my many thanks to him, YamFazMan had addressed a comparable problem for the Start 25 in May 2018 in third listed entry at:
Following his suggestion for “boosting the GPS signal,” I investigated purchasing a GPS Re-Radiating Antenna Signal Wireless SBG-190.
This item is apparently manufactured by Gainwise Technology Co., Ltd. in Tainan City, Taiwan. See:
The “manual” for this item is available for “download” (in each of English and Chinese) at:
(the “website” may take some time to fully download its files for further downloading)
I found this item was available for sale in the USA from:
6847 S. Eastern Avenue, #104
Las Vegas, NV 89119, USA
(See: https://www.gpscity.com/gps-city-itrek-gps-re-radiating-antenna-sbg-190 )
Please note the SKU Number is: ITREKSBG190
Please also note the price is USD 49.95 plus “free shipping” in the USA.
Please likewise note this USA price is at more than a 95% Discount (!) over that in the United Kingdom at:
(this was shown as an informational “link” in YamFazman’s entry, without any “endorsement” on his part, of course!)
I purchased this GPS City iTrek GPS Re-Radiating Antenna SBG-190 from GPS City and it was timely delivered. I installed the “External Active Antenna” (which has a “magnetic base”) on the left rear metal roof of this SUV and the “Radiator (Internal)” (which is the broadcasting antenna) on the inside edge of the front passenger seat headrest, having inserted the “SBG-190 Module“ (which is the power unit) in a power receptacle on the rear of the console panel facing the rear seats.
The GPS Signal was then received as it should be on my GO600 and my GO600 then “worked” as it had in the past.
I hope this is of help. Again, many thanks to YamFazman for his suggestion!
