Willy, February 7, 2013 Generally satisfied. Extension does increase signal strength by about 10%. Suction cups are not very reliable in cold weather -20C. I am looking for better perhaps larger cups.
Glenn, February 5, 2013 I could not get the trafic data on my GPS add the external
antenna it now works great.
06 Duramax, December 17, 2012 Two of my trucks seem to have problems with the signal
strength/reception of the traffic data on my Garmin Nuvi 3590.
The reception is fine on the other three vehicles. The Garmin
Antenna Extension Cable fixed the problem. All the vehicles
now get the same reception.
Greg, November 19, 2012 You get exactly what is pictured. I connected it to my GPS
and see no noticeable difference in the receipt of traffic
data. HOWEVER, I have no way of telling it is actually does
make an improvement.
Would I but it again? Sure!
