Best sat nav

Google maps or Waze apps on your phone. Get one of those suction mobile phone holders for your windscreen if your car don't have apple car play or android auto.

It does zoom in and tell you what lane to use

As you haven't done that drive before, I think your biggest enemy will be fatigue.

It's a solid three hour dirve on a good day, and if you're not used to it, you might not feel yourself getting tired. I'm very used to driving across the country and 2.5 - 3 hours is really my limit in a comfortable car before I need to take a break.

Preempt getting tired by planning I'd say 2 stops along the way if you aren't used to it. Get a coffee, or keep a bottle of Coke or Red Bull in the car to give you boost if you need it along the way.

Remember to have a phone charging cable in the car too, 3+ hours of Sat Nav will run it down quickly.

I had this car holder and it's pretty good as it doesn't bounce around too much. https://www.gomibo.ie/accessory-detail/belkin-f8m978bt-universal-car-holder-black

Waze app on a phone is the best option.

Standalone satellite navigation units are a thing of the past.

I have used nothing but these phone holders for years. No suction disc to fall off regularly and doesn't block your view. Used every day and replaced around 4 years when they often start to lose their grip.

Also I use google maps at home and abroad....Car and Bike. Probably the best free navigation app out there. I have tried Waze, and Sygic (Sygic is a paid App, very good for offline use, but Google Maps beats it with it's numerous free features).

Some newer cars have android auto or apple car play. You connect phone to car typically using a usb cable and the Google maps sat nav appears on the car radio. This gives you a bigger screen and is easier to use.

I use my phone and also a tomtom sav nav that I bought around 2015 for around 120 euro.

The tomtom is better to use but google maps is more up to date and you can find lots of things like businesses that arent available on the tomtom.

you should check the route on google maps and use street view to see what lanes you should be in etc before the trip, this will make things easier for the trip.

I have old radio and a cassette tape player

Use Google maps. Leave early and if you go wrong it'll reroute you.

Fax me the details.

Google maps is great.

To become accustomed with Google Maps, use it on a few local trips before the airport trip. You will learn how 'she' gives instructions and directions.

As another poster said make sure you bring a cable for charging.

Best of luck.

No problem. good luck with the trip.

Also, don't forget the obvious - the signposts! Keep an eye on them.

Also, make a post-it note of the road numbers you will be using e.g.

R103 - N27 - N31 - N2 - M2 etc

Another post-it in reverse for the trip home.

I had a lot of issues with the suction grip on the phone holder coming loose. Then I cleaned the window (properly) and it's no longer an issue !!

My car has built in Sat Nav and I have a Garmin Sat Nav. Never use either of these, it's always Google Maps.
