Well mine has (a 95) and reception's crap compared to it being at the side of the roof on the UK model, is there anything I can do apart from drilling new holes and getting the proper side mount

theres some bee stings that are amplified, you could find and use one of them types, basically the base has the normal aerial coax on it and 1 other wire which you wire to the electric aerial out on the stereo or the amp remote wire, any wire that has an acc+ feed

 

or do what i have done and buy a DAB radio

Do you have the band adaptor connected to the back of the head unit ?

I may be wrong but when i put new radio in the eunos i had to attach a mw/lw band adaptor to pick up uk fm freq as the japanese don't pump out as much wattage when it comes to radio reception

I may be talking absloute b******s as it was 4 yeas ago when i changed it
