in the end, the European Union executive was unable to accept them before the deadline for sending the "statement of objections," which lays out competition problems with the deal.
A spokesman for the European Commission declined comment.
"The European Commission never comments on ongoing merger investigations," said Jonathan Todd.
The statement does not, however, mean the deal will be rejected. Instead, it means that TomTom will have to come up with better remedies. The deadline for a decision is May 5.
Experts say that if a statement of objections is issued it slows and complicates the process because it creates a formal, written record of problems with the deal.
The deal would let TomTom move beyond hardware where double-digit profit margins are expected to decline in line with other consumer electronics makers, analysts said.
Tele Atlas also supplies online mapping Web sites such as Google Maps as well as mobile phone maker Nokia.
TomTom and Tele Atlas said when the deal was announced they planned to tap into TomTom's user base to get feedback on where maps were out of date and gather statistical information on traffic flows to create new features such as daily map updates and predicting traffic jams.
