I-Astro 430 Kuyinto emisha yakamuva evela enkampanini yakwaGarmin, edale uhlelo lokusebenza oluvumela izinja ukuthi zilandelwe yi-GPS, ukuze zingalahleki. Kube nezinhlelo eziningi zalolu hlobo, kepha kunalokho ziqondiswe kubantu ngabanye. Kulesi senzakalo sithola ithuluzi elihlose kakhulu izinja ezisebenzayo, ngoba lisivumela ukulawula izinja ezingafika kuma-20.
Le divayisi entsha, efaka ikhola nge Uhlelo lwe-GPS futhi ngohlelo lokusebenza esingakulawula kusuka kudivayisi yeGarmin, noma ngabe iwashi, esikrinini esikhulu noma esincane. Leli ithuluzi eliphelele uma sikhuluma ngezinja eziqondisayo, izinja zokutakula noma ezisebenzayo, ezingalahleka ezimweni ezithile. Kusengaphambili okunye ukunakekela ezethu ezinoboya.
Iqiniso ukuthi yonke idivayisi iyama ukubhekwa kwezinja ngohlelo lwe-GPS kuyabiza impela, ngoba amakhola abiza ngaphezu kwama-euro angama-700, futhi ayatholakala ngosayizi ababili, ngezinja ezinkulu nezincane. Ngaphezu kwalokho, kuzodingeka uthenge isikrini noma enye yamadivayisi ukuze ukwazi ukubona ukuma kwezinja, ezifinyelela kumakhilomitha ayi-14 ukusuka lapho. Ngaphezu kwalokho, lesi siginali sibuyekezwa njalo ngemizuzwana engu-2,5 ukuze sikwazi ukulawula inja. Futhi imigexo nayo inesibani se-LED ukuze ikwazi ukuyithola ngisho nasebusuku.
Ngaphandle kokungabaza kuyidivayisi okungewona wonke umuntu ongakwazi ukuyilawula inja nge-GPS. Kungumqondo ovumeleke kakhudlwana we amaphoyisa noma izinja ezisebenzayo, lapho ufuna ukutshala khona le mali ukuze ulawule isikhundla sakho ngaso sonke isikhathi. Ungakhohlwa ukuthi i-Astro 430 ivumela izinja ezifika ku-20 ezahlukahlukene ukuthi ziqashwe, yize kuzodingeka ukuthi sitshale imali kuzinsika zazo sonke. Kungumqondo woqobo impela yize uqondiswe kakhulu kochwepheshe.
