antenna booster works

[kizza1]

A little while ago i upgraded my headunit from a factory unit to an ebay special "tun7k gps unit" ever since i did i havent been able to get nova radio station on the sunshine coast.
I have tried an antenna booster on another car before without any success. With mixed reports on the internet i thought id give another one a go.I went with a "dig options" one as they seem to have good reports.http://www.ebay.com.au/itm/AM-FM-Signal-Amplifier-Booster-Radio-Stereo-Car-Antenna-DIN-to-DIN-Honda-Holden-/261166458789?hash=item3ccebbe7a5
and the results:
I connected it at home. I checked 4 channels before and after install.
Now i can get nova. I would guess theres about a 20% increase in signal throughout the channels.
I would say its back to how the original factory units reception was.
I have no connection to the seller on ebay i just thought if anyone else had the same dramas they might want to know the results before purchasing one.
