It is quite random, I was looking to get to Kerry Regional Airport, but the satnav will not permit the entry of Farrenfore, the town where the airport is located . I was then surprised that is accepted Tourmakeady, which was unexpected. It does not accept the Irish postcodes(Eircodes), although it does accept those of other countries( UK and Netherlands at least).
My understanding is that all satnavs actually perform their guidance/ route directions by the sole use of the latitude and longitude of the start and finish points. If a location identifier in the form of a post code or address is entered into the satnav, these location identifiers have to be first converted in the satnav unit by a look up table, or an algorithm, into the corresponding lat and long values before the route can be planned and subsequently used for guidance.
Consequently, although it may be convenient to enter a post code or an address into the satnav, it is not the only method and the same route planning and guidance is available by entering the latitude and longitude values corresponding to the destination.
For the area that you mention - Westport, Mayo, I see various hotels etc that have an internet presence - these often give the latitude and longitude in addition to the address and Eircode...Presumably this is to assistance users of Satnavs which cannot cope with Eircodes.
In any event the latitude and longitude can be looked up at this web site which seems to cope with locations worldwide:
So using this web site for your example of one of your problem locations - Kerry Airport - the lat and long value can be found just be entering Kerry Airport, Ireland into the address box and the full address is returned as "Kerry Airport, Farranfore, Kerry, Ireland", together with the latitude in "Degrees - Minute - Seconds" format, given as 52 - 10 - 53 N, and the longitude given as 9 - 32 - 14 W
The actual effort then required for setting the destination into the Cactus Satnav is to enter the six digits for longitude and the five for longitude into the specific lat and long boxes on the screen, so this is not greatly different from entering an address, letter by letter, or an Eircode .
The User manual explains the Navigation menu sequence to reach the latitude and longitude entry screen. I tried the method and it seems straightforward.
