Have bought a navigation system from Becker. After 1 year, the unit will already broken (Monthly use: 1 times) so after 12 Navigation processes break down the Becker navigation systems. So I wanted to redeem the entire warranty. Since I unfortunately do not have any more cash voucher (According to lawmakers unnecessary !!!!) I have submitted an affidavit (If false testimony could face up to 3 years in prison, every court in Germany to recognize such !!!) only the company Becker not !
I have learned from them so never buy bad products from Becker again. Absolutely not recommended.
