Welcome to the Raymarine Forum EM,

Q1. I called westmarine and they told me to buy the CP370 and install it with the CPT-100 transducer. Is this perception ok? What are the pros or cons? Will this combo work perfect?
A1. CHIRP/DownVision Transducers (ex. CPT-100) are not compatible with the CP370 1kW 50kHz/200kHz Sounder Module. While the recommendation to add a CP370 to support operation in depth greater than those which would be supported by the RV transducers, the CP370 would need to be interfaced to one of the 600W or 1kW transducer's found here.

Q2. When I got the equipment I told west marine I need Navionics + for Gulf Coast of México, they sent US card, they are asking me to call raymarine and make the swap directly, you think this will work?
A2. This was either an incorrect recommendation or you have misunderstood the WM salesman. Please click here to view a FAQ addressing this subject. As indicated within the reference FAQ, the chart card is pre-populated with navigational cartography for US and Canadian waters and may SonarCharts may be added to the chart card for local waters. Alternatively, the MFD may be purchased without a Navionics+ chart card and then a Navionics Platinum Plus chart card providing coverage for the area of operation may be purchased from an authorized Navionics Dealer.

Q3. At some points of the fishing trip, the transducer is sending some crazy information to the display, attached is the picture, any thoughts on the causes? Maybe bad installation or interference?
A3. What was the charted depth of the water when this problem was observed? How fast was the vessel moving when this problem was observed? When the vessel is adrift, engines in neutral, and engine RPMs increased, is any noise observed within the sonar plot?
