Am updating to LH3 V3.9.46 primarily for the long delayed sailing/layline benefits (Thanks so much for getting these out!)

I had installed the Evolution autopilot and P70 last year, a great improvement in autopilot performance.

Noted there is a new software update for the p70, that amongst other things changes the steer by wind command. The downloaded update is Ray_Pilot-Web.update.iso. there is also a boot-web upgrade.

I also noted that the LH3 V3.9.46 package also includes a file: ray_Instruments20190104.upgrade.

My questions are:

1. Does the V3.9.46 package for the upgrade include the P70 updates for my P70?
2. I sail, do I need this P70 upgrade?
3. Is the separate "Boot-Web" update also required?
4. Could I get instructions, protocol for insulating the P70 update? e.g.can I add these two files to the V3.9.46 .iso set so they can be installed when I update? if not, how to i install the two iso's?

Welcome to the Raymarine Forum Bob,

Q1. Does the V3.9.46 package for the upgrade include the P70 updates for my P70?
A1. Yes.

Q2. I sail, do I need this P70 upgrade?
A2. While the latest p70 software update (v3.08) is not required for wind vane mode, it is recommended that this update be installed to make access to wind vane mode easier.

Q3. Is the separate "Boot-Web" update also required?
A3. Negative

Q4. Could I get instructions, protocol for insulating the P70 update? e.g.can I add these two files to the V3.9.46 .iso set so they can be installed when I update? if not, how to i install the two iso's?
A4. This step is not required. All one need do is extract ALL files within the downloaded LightHouse 3 v3.9.46 to a microSD memory card, inset the card into the MFD's memory card reader, and after the MFD detects that software updates are available, then choose to update the p70's software.
