Garmin 545s Help ?

I just purchased a Garmin 545s and have several questions:
1) Is it correct that the transducer supplied is for both the speed & sonar?
2) A seperate speed sensor will not be required, correct?
3) Am I correct that the alarm relay is built into the display Unit?
4) Looking at the Pin Assignment and wiring harness layout on page 49 of the instruction manual it appears that I must connect both the RED & YELLOW to the POSITIVE (+) DC Power Source and the BLACK to the NEGATIVE (-) Power Source. The remaining wires are not used unless other devices are added later. Is this correct?
5) there are two male 19 pin connectors on the back or the display unit. The harness that came with the unit only appears to fit into the connector to the left, vs. center. I assume the connector to the left is the correct one to use, or should I be able to use either one ?

The only two wires you need to connect for basic operations is the red (to power source) and black to (ground).
Here's the answer to your cable question.
What transducer came with your unit?
Make sure you go to the Garmin website and download all the software updates. The latest is V4.3.

Tom, this is the transducer that came with the unit
I didn't think to buy an SD card. I assume I'll need that to update any software? Do you know what the largest/best size card is that I should buy?
Is there seperate software that you download from Garmin in order to chart courses on a PC or how does that work? I didn't get any software discs. with the unit.
This is a refurbished unit that I bought. It's absolutely perfect visually. If it works it was a real cost savings!

The transducer is for both sonar and water temp. The speed is calculated from the GPS that has a built in antenna.

Ah, forgot all about the GPS calculating speed! Thank you.

I use a cheap 2 gig SD card. That is more than enough for our needs. When you get your card first put it in your unit , THEN power up your unit. This will format your card. After that load the update on the card (using a card reader/writer) from the Garmin website. Take the card put it in the unit and follow the prompts and your unit will be upgraded.

I finally got around to buying an SD card and updated my Garmin 545S with the latest software. I had no problems doing the download/upload but I'm confused as to what I'm to be seeing or supposed to be able to do on the PC (computer).
The only thing I have been able to access is the 'Mapsource' software. I can set routes, waypoints etc. using this program but it appears to be configured to use with the cars Garmin gps. When I try to enter a route on the 'water' the next point on the route automatically goes to the closest street. I'm trying to navigate the ICW so ther are a lot of adjacent streets.
Am I missing software or just don't know what I'm doing? I have not purchased any of the Blue Chart software.
I haven't been on the water with it yet so I don't know what I'm going to experience there either.

I think you have the wrong Mapsource. You are correct, you need the Blue Chart software.

Is there a different Mapsource version for marine navigation vs. land? Can't I do any routing etc. on the PC without the Blue Chart software?

Use the Trip and Waypoint Program that's embedded in Map Source. After opening Map Source look to the upper left area under the Top MEnu Bar. You'll see a drop window. Clcik on the down arrow adn choose the Trip and Waypoint Program.
You can enter all the waypoints and routes you wan to.

Thanks Tom, I'll give it a try.

I can plot waypoints and tracks but routes are hopeless. It always jumps to the closest road.
