I know that this subject has been mentioned frequently in the general forum as having a stubby aerial seemed to be a must for many Z4 owners. I kept seeing the discussions but could not really see why people bothered. However, someone recently (sorry I cannot link to the post as I have searched for it without luck) mentioned that a Peugot stubby works really well. Details are Peugeot short aerial
Part number 6561 N3 65mm Long. I contacted my local dealer and he said it cost about £5.50. I am sure you can get it for less on ebay but I could not be bothered. I ordered the part and screwed it on a couple of days ago. It is a direct replacement for the BMW provided aerial and it seems to work perfectly in the 2009 Z4 with the nav system. I must confess that it does look a lot better and I am now a firm convert to the stubby brigade.
