We went through the same iterations in mid 2014 when our current boat was new to us...
We bought it knowing it needed a new RADAR, and I wasn't enamored of the Win XP dependent navigation
system, so... we ended up choosing B&G also.
Before I respond with my strategy, let me share our thinking and decisions at that time, which will bring us to today:
The 4G RADAR was a no-brainer [and we are still very happy with that choice...]
When we were buying
, the Zeus2 was announced ['imminent'] but not yet available... and didn't hit the shelves for another 6 months after that... We waited as long as we could, and ended up with the Zeus Touch using Navionics charts
We are very pleased with the Zeus Touch system, but are still considering adding a Zeus2 to the mix. Why? No black box needed for their forward looking SONAR and autopilot computers
, and the GoFree WiFi
functionality is built-in. [Which is good and bad considering we are on our 3rd GoFree and counting- all replaced under warranty...]
We also intend to upgrade the instruments with the Triton2 line replacing our aging [but still fully functional] Autohelm
Later we replaced a back-up, non-DSC VHF radio
with the B&G V50 with wireless mike. Another good choice, and it is now our primary VHF
So with that background, and my mention of being on our 3rd GoFree, we have experienced a few upgrade/support iterations with B&G [Navico...]
I also come from a technical background, and need to set your expectations to cruising speed with regard to support, response times, and updates with consumer marine electronics... It ain't the same as what you may be used to dealing with the likes of Cisco, etc.
Sometimes their well intentioned support staff just don't know themselves, or worse, give out the wrong information. But most of the time they are great and get it done.
The ability to upgrade the firmware is a great feature. I have been through several of those cycles too. One pattern I've noticed is once a line is replaced by the newer generation, they seem to stop firmware updates for the prior generation(s). e.g., I haven't seen a firmware upgrade for the Zeus Touch in over 2 years, but there have been several for the Zeus2, and even VHF radio
and wireless remote
And here is another odd rub; not all the devices can be upgraded on site. e.g., there was a bug in the VHF radio that took them several months to squash... [It liked to randomly 'play' the Wx channel while on 16; not switch, just play...] The downloaded firmware update worked great for the radio, but I had to send the wireless mike to B&G to have it upgraded to make it work with the upgraded radio... I don't know if there is other hardware
with this requirement, but thought I would mention it from personal experience...
Given this specific experience, and how long it can take to resolve issues [e.g. an average 30 day turnaround time before a new GoFree wifi
unit was replaced...] I would go with what is available now and get it/keep it all working if I wasn't planing to cruise
at the dock
in large city with support infrastructure...
I say this being very happy with the choices I have made, but with a touch of caution. [And no, I'm not one of those IT curmudgeons who conservatively waits a year or two before applying an update...]
Best wishes executing the ideal strategy for your needs.
