The 305 comes with the heart monitor, and the 205 doesn’t.
AND….
The 305 is compatible with the optional cadence sensor (for biking).
The 305 is compatible with the optional foot pod (for indoor use, e.g. treadmill or indoor track).
The 305 is obviously red while the 205 is blue.
You cannot upgrade the 205 to any of the above (including heart monitor) after-the-fact.
I don’t see a Bravo back-up camera listed at Wal-Mart’s website. However, I highly doubt the nuvi 200 could act as a display for the camera. The only input/output connection on the nuvi 200 is the mini-USB connector on the back. Even if you could use that connection to interface with the Bravo camera, the nuvi 200 has no idea how to talk to the Bravo. It doesn’t know the Bravo exists and doesn’t know how to talk to it. The nuvi 200 was designed to be a basic navigation device and they didn’t have reverse cameras in mind when engineering the nuvi 200. It will give turn-by-turn directions and display photos you load into its memory from your computer, but that’s it.
I’m getting the Garmin Forerunner 405. Is it worth it to spend the extra 50 dollars for the one with the heart rate monitor?
I know the wrist monitor is rechargeable, but was wondering about the heart rate chest strap. Is the battery in it replaceable or do you have to send it off for replacement as the many chest straps I have owned in the past only last between 1 1/2 to 2 years. Also, when you download your info on the site does your running course with street names automatically load?
I want to use it for counting calories burned during jumping rope and Wii Fit.
