Tracker radio interference

Hi, I'm from the Peak District and have a Defender 90. People occasionally come around wearing balaclavas in the middle of the night trying to steal it. The last time this happened a couple of weeks ago I wasn't in so they paid a visit a couple of doors down and drove off in their new car. So I had a tracker fitted yesterday but it creates a lot of interference with the radio. I posted a thread about it then realised it was in the "Introduce Yourself" forum. Looks like I can't delete it or change the title though, so I've edited the content to be more of an introduction. The heading should probably be "Hi!" or something.

Yer may need to ask the peeps who supplied or fitted it. They normally work oft gprs but the antenna is very small. If it's close to the radio it may need moved away from it a bit.
