Re: Shark Fin Antenna question
Yes the 2014 shark fin antenna can be used on a 2011-2013 that typically has the base / mast style antenna.
However some minor modifications are needed.
Also, if your vehicle has Sirius and navigation, make sure you get the right antenna.
Part 5091902AA is a 2014 Grand Cherokee antenna, texture finish, that uses the green and white fakra connectors only. This will only work on your 2011-2013 Grand Cherokee if your factory antenna is not amplified, and does not need Sirrius or NAV. It will only have two wires, white connector for AM/FM and green connector for SIRRIUS (NAV too if later 2011 -2013)
SOME 2011 Grand Cherokees (built before Jan 2011) that came with the RER radio, have a separate NAV antenna under the dash.
The RER radio has 3 FAKRA inputs (blue for NAV, Green for SIRRIUS, and White for AM/FM)
If this is you, and you upgraded to the RHR and are using the signal combiner for the Sirrius (green) NAV (blue) signals to combine into the one green input on the RHR, You will no longer need the signal combiner if you get the 2014 antenna 5091352AC. (AA and AB also available, but AC is the newest version)
The difference with the 5091352 versus the 5091902 are what signals it receives and the connector types.
If your 2011-2013 has 3 wires, you'll need the 5091352. There are other part numbers for the painted shark fin antennas but I don't know all of them.
However, these antennas have the double blue fakra connector (green wire for Sirrius AND NAV, and the black wire for power) BOTH in the same blue connector.
The white AM/FM connector is unchanged.
You will need a double FAKRA C male connector to single FAKRA K female / with the other wire being cut off and butt connected to the gray w/red tracer power wire in the roof your wk2.
This male double connector will plug into the antenna double blue female, and split into two wires. Again green wire in the blue double connector will go to the green in your roof, and the black wire is power only so it gets butt spliced to the gray wire in roof.
The white am/fm is a direct plug and play.
This antenna will now carry Sirrius and NAV on the green wire, AM/FM on the white and gray wire / power for the amplified antenna.
Can be done but is quite picky with the connectors
