ICOM ADAPTER PLATE - M5xx to M323 / 423 - suggest use with MB-132 New Mounting Bracket to help customers to upgrade to Icom’s latest range of fixed VHF/DSC Marine Radios. With the introduction of our next generation range of fixed mount VHF/DSC we appreciate that many Icom owners will want to upgrade from previous models. Replacing older models such as the IC-M59, IC-M401 or IC-M411/IC-M421 with the IC-M323/ IC-M423 is relatively straightforward as all the previous models are smaller and you will only need to trim the hole. However if you have a model which is larger or has a different shape such as the IC-M501, IC-M503, DS-100 or IC-M505 the gap will be much larger. To solve this problem Icom UK have sourced a black frost acrylic mounting bracket which when used with the optional MB-132 flush mount kit*, will allow you to cleanly install either the IC-M323 or IC-M423 where a larger icom radio once sat. This new mounting bracket is simple to fit and has been tested by many boatbuilders. |
