What GPS do you have? What has your experience been like? Why (or why not) do you recommend this unit or brand?

I am looking to buy my fiancee a GPS for her birthday. We also love golf and have considered getting a GPS for golfing alone. That said, is there a GPS out there that could double as a “most of the time” in-car GPS system and then could get pulled easily from the car and put into our golf cart at the course? Price is not a huge object (though I don’t have an infinite budget). The main feature is the in-car GPS, but I would love to get one that could be used on the course as well with pretty widerange course map support. Thanks in advance!!!
