Review on Detroit Packing Co. High Gain 28dB Magnetic External GPS Antenna Cable - 7.5m (25ft) Straight SMB Female Connector - Compatible with Verizon Samsung 3G Network Extender by Greg Mahoney

Instead of replacing a broken Audi Sharkfin GPS antenna (dealer wanted $800) I just unplugged the stock antenna on the back of the radio. I then hooked up the spare GPS antenna to the back of the radio and found a suitable location for the receiver above the glove box and just below the dash. Worked perfectly. Hard to beat for the price. A $10 solution that works just as well as an $800 dealer solution!
