Renault Radio - Poor Signal compared to other cars

[katonna]

I have a Megane CC 2008 with an update list radio.

My sister has a Clio 2002 with a tuner list radio.

BOTH suffer from really poor radio signal.

However other friends and families cars (Mostly Honda) who live in the same hilly area as us seem to get a fantastic signal.

How on earth do I fix this, or is it just that Renaults have shite radio receiving capabilities when compared to other makes of car.

I saw on here that someone suggested to remove the aerial and sand the earthing connector to help it, but I haven't had the chance to get to the aerials on either car yet. Opinions on this.......?

If anyone can help then I'd really appreciate it. This is constantly driving my sister and I mad.

I had a similar problem on my cc
It turned out that the radio mast was damaged (I replaced it and bingo, works fine now) may be worth borrowing one from someone and seeing if it makes any difference before splashing out though..
