Looking at purchasing a new sounder and gps for my boat and just wondering if anyone out there can help me with cutout dimensions for a furuno 585. i already have a cutout in the centre console from an old sounder and trying to work out whether one will fit. if anyone has a 585 installed and knows the dimensions of there cutout would be much appreciated.

also not being very electronically minded would like to leave it to the proffesionals. anyone know a rough guestimate of cost of install and if anyone can reccomend somebody that does a good job?

cheers,
chris
