Garmin nüvi 3790
Garmin recently launched this unit, and I’ve been testing one for the past few months. It’s a sexylooking device: thinner than previous models, with a nice, clear screen.
It tends to get quite warm, but this is normal for thin electronic devices.
I’m impressed with the “estimated time to destination” function. On a recent trip from Durban to Johannesburg it was spot on. It must be designed to take into account stops for fuel, tolls and so on.
RAM windscreen mount
The windscreen mount that comes with your GPS might be fine for the N2, but it could slip off on a corrugated dirt road. I like this RAM mount, because it has a much bigger suction cup than other mounts, plus it comes with a 25-year warranty.
When you use a GPS unit inside a vehicle, the roof can block signal reception from satellites. An external antenna mounted on the roof will in most cases give you full signal. Garmin has two models: the GA 25BNC and the GA 25MCX. Check which one works with your GPS; not all Garmin models are necessarily compatible with either one.
