The reception in the MG/75 is not the best, but it shouldn't be terrible unless there is something seriously amiss.

My guess would be the amp attached to the HRW is not as well designed as it could be and its output is weak.

Why I have arrived at this conclusion is that years ago when I replaced my Hi-line system with the early Radioguy unit, the unit needed the signal splitting between the radio and the navigation system for receiving traffic updates. A simple passive splitter wrecked both the radio reception and nav systems reception. I ended up fitting an active splitter which made things very much better.

That opinion was further confirmed by the fact that I also noted that reception on the new unit was not as good as it had been on the Hi-Line. The Hi-line receiver was boot mounted, the new unit dash mounted with the antenna lead needing to be extended to the front, so the extra losses in the antenna extension lead made reception worse.

So it would probably worth buying a cheap pre-amp and fitting it between the HRW amp, and your antenna lead going to the front of the car.

Fix a poor handbrake; DIY ABS diagnostic unit; Loan of the spanner needed to change the CDT belts; free OBD diagnostics +MAF; Correct Bosch MAF cheap; DVB-T install in an ex-hi-line system; DD install with a HK amp; FBH servicing.

I've taken a vow of poverty. To annoy me, send money.
