Pioneer Corp in Tokyo appears to have been the most prominent victim of the planned alterations to global positioning system satellite services over the weekend. On Sunday the company is said to have received 2,000 calls complaining that its car navigation devices either did not work or showed the wrong locations. Around 50,000 more Pioneer units are still out on the roads, the company said. Users must take the devices into a repair shop for fixing. Around 5 million GPS systems are in use within cars in Japan, but only 340,000 are the old-style systems affected by the changes. None were exported. Pioneer made 270,000 of those units. It has known for a year about the changes, but managed to persuade only 150,000 customers to bring in their systems for a repair ahead of time. The situation has been cited as an indication of what could happen for Y2K. รก
