Then bugging DaveDND for a modulator that I can hardwire in- which he doesn't usually recommend due to the poor signal strength.
Ok, that needs some clarification then.
An external aerial works better than an internal one - that we all know, and the internal aerial on the Omega has a booster in line as the signal is often so poorly received the head unit simply cannot sense it and any further joints or circuitry in-line with this poor signal may lead to the complete loss of radio reception - modulator will work fine, but radio reception would be significantly impaired.
Whether you want to use a wired modulator (no problems with that), or to improve the radio reception, my advice would always be the same - ditch the internal aerial and booster and fit an ordinary and decent antenna on the roof (from around £10) - For those of you making use of the extensive electronics, then Bosch and Hirschmann both do some excellent combined FM/GSM/GPS aerials that look identical to the standard one - prices anywhere around the £50 ~ £125 mark.
It makes me laugh to think that GM put an internal aerial with a booster inside the car to retain the sleek styling and cosmetic appearance of the car, and then thought, Oops! we still need another aerial on the roof for the phone, why they never combined it in the first place is beyond me.
