Unfortunately, the pads have not kept with me long. The first pad I immediately after sticking my navigator (Navigon 40) attached by suction cup on it - it did unfortunately only 1 day, then the pad sparked by the dashboard. The 2nd pad (in the package are 2 pieces included) I've pasted after thorough cleansing of Amaturenbretts, and waited about 1 day with the Navi-assembly. This time it held a little longer, namely about 4-5 weeks. As it was then for the first time really warm (25 ° C), also the 2nd pad falls off the dashboard. But is certainly a question of the nature of the Amaturenbretts, for me it was a Seat Alhambra, of 2006.
