The frequency used for the key fob for Ferraris is different in Europe vs. the US. But Ferrari doesn't change the length of the antenna to compensate for US cars. When I owned an F430 and later a 360, there was DIY on fixing this problem: Ferrari 360: Fitting a battery tender and improving the range of the remote control fob | Aldous Voice My question: where is the antenna located on the 2008-2013 California? Thanks! Tom
