iSuppli forecasts substantial growth in the off-board navigation market, estimating the user base will grow from 62 million today to 263 million by 2014, generating $9.7 billion annually. Google Maps Navigation is expected to dominate with its free, ad-supported model. However, Google faces challenges from privacy concerns and competition from Nokia and Motorola who are developing their own navigation solutions. iSuppli has increased its revenue forecast for the global electronics manufacturing industry due to stronger-than-expected growth in 2010, but sees challenges for ODM profitability as margins decline.
