Well here are the results of my Yorkshire trip. I have pannier lights, lower front fog lights, Garmin 2820 GPS and a CB installed! Ian did a fantastic job and it’s obvious he is a careful workman who knows what he is doing. Everything seems to work OK although there is a bit of alternator whine on the intercom circuit. Ian thinks it is probably the CB that is doing it but we haven’t yet bottomed it out. The noise is not very loud and with any music playing, it is drowned out.
The Garmin 2820 is quite capable unit although I miss some of the features I am used to on the TomToms like quick alternative route selection. The Garmin does allow one’s own routes to be loaded onto it and it will also record a track log which are the reasons why I wanted this unit.
