We've often found (regardless of data based systems or voice only setups) that the majority of issues result from bad equipment setup. The biggest of these been
aerial problems. A few simple steps can ensure your aerial is not an issue:
1) Make sure your aerial is in the the best possible position (or as close as possible). This is the highest point of your car. Usually the very centre of the roof of your car. If you can't get it in the centre then try to get it as close to the centre along the central line of your car (marked in blue on the picture).

2) Ensure your aerial to radio connection is in good condition and the length of your aerial cable is intact and cut free. If there are cuts in your cable replace your aerial. Whilst it is possible to repair a damaged cable by and large it does not make financial sense. In addition moisture/water has usual got in and will have started to corrode your aerial.
3) Make sure your aerial is the best possible type for the system you are using. Make sure the base of the aerial is a solid one (many of the cheaper aerials have an air gap inside which reduces performance). Also take care not to use a "booster aerial" if using a data system (booster aerials have a tendency to to scrabble the data and make for poor performance).
4) Finally if you've checked all these and are still having problems have it checked by a radio specialist.
