There is instruction available on dozens of languages

Luckily we had learned our lesson by then and ignored the GPS instructions

I was not sure if it installed right, but as soon as we got into our rental car, it found our location and gave excellent instructions

Simple instructions would have been very helpful.

NOTHING by way of step-wise instructions on installing the card.

Porto to Nazere to the Algarve to Lisbon - clear driving instruction and displays.

[I do seriously fault Garmin for their complete lack of step-wise instructions.
