I drove N134 from the Spanish border to Pau. It's signed all the way but it's routed through Oloron-Sainte Marie. OSM and GM confirm it.#
A waypoint at N134/D55 roundabout south of the town is missing because Pau is signed via the bypass.
E7 is signed south of Oloron-Sainte Marie but I couldn't spot any E7 sign from the D55 roundabout to Pau. The D55 sign to the bypass is w/o E7 but GM still indicates the bypass E7.
I saw the next E7 sign on A64 towards A65 but I drove N134.
