I have the Garmin 182 with the LI BlueChart chip. Great detail and always get a good initial lock. I would flush mount with a remote antenna. If you go with the internal antenna, you will want to mount with the bracket. I have had very poor customer service with Raytheon. On another board, the florida boaters who get a lot more use from their electronics, rate Garmin #1 for GPS, Raytheon # 1 for Radar, and Furno #1 for bottom machines.
