I'm planning on buying a car GPSr, probably a Garmin, but open to suggestions. Currently I have street maps loaded on my 400t and use that to navigate. What I would love is to be able to load a car GPS with geocaches and use that to navigate by street to the GZ. So...

Can you load any car GPS with caches? Are some brands easier than others?

Are there any that wouldn't require me use GSAK? The ideal would be if I could download my PQs directly like I do with the Oregon.

Will certain models hold more caches than others?

Any suggestions?

Thanks everyone.
