GoalAn affordable GPS unit for automobiles that contains all the features you need for nav and music listening. All built-in and no plugging required
State of MarketAlmost all affordable units in stores do not contain MP3 player features, I believe because it would cut into sales of aftermarket head units. You can usually only find the feature through an online order. I have not tried other brands, as most of the features I require I've so far only seen in Garmin. Over the years, there are only a few models available that have all the features at any given time. Also, units with lifetime maps do not have MP3 features. The one unit that does have both does not have a line out port, making the MP3 player useless.
- Line out/head phone connector
- Dock connector
- Muti-point nav with importing via GPX
- SD card slot
ScenariosWhen starting your car, the GPS receives power, and boots up to the main screen. The MP3 player was playing your playlist when you turned off the car, so it resumes in the background, playing from your SD card with your entire music collection on it. You can choose a destination and the routing commands pause the music to speak.
If you want to create a custom route, such as for a car club, you can prepare it before hand. You can do this on the unit itself, or using tools such as Google maps and a converter to GPX. The unit only holds 10 routes ready, but can have as many GPX files staged for import as needed.
