Abstract

There is provided an in-vehicle electronic apparatus that can attach a portable electronic apparatus having a first GPS antenna receiving a GPS signal and a GPS receiver connectable to the first GPS antenna. The in-vehicle electronic apparatus includes a second GPS antenna receiving the GPS signal. When the portable electronic apparatus is attached to the in-vehicle electronic apparatus, the GPS signal received by the second GPS antenna is output to the GPS receiver.

Claims

1. An in-vehicle electronic apparatus that can attach a portable electronic apparatus having a first GPS antenna receiving a GPS signal and a GPS receiver connectable to the first GPS antenna,

the in-vehicle electronic apparatus comprising a second GPS antenna receiving the GPS signal,

wherein when the portable electronic apparatus is attached to the in-vehicle electronic apparatus, the GPS signal received by the second GPS antenna is output to the GPS receiver.

2. An in-vehicle electronic system having a portable electronic apparatus and an in-vehicle electronic apparatus that can attach the portable electronic apparatus,

wherein:

the in-vehicle electronic apparatus comprises an in-vehicle electronic apparatus side GPS antenna receiving a GPS signal; and

the portable electronic apparatus comprises;

a portable electronic apparatus side GPS antenna receiving the GPS signal;

a GPS receiver into which the GPS signal received by the portable electronic apparatus side GPS antenna receiving the GPS signal or the GPS signal received by the in-vehicle electronic apparatus side GPS antenna is input;

a detecting portion detecting that the portable electronic apparatus is attached to the in-vehicle electronic apparatus; and

a switching portion changing a signal to be input into the GPS receiver to one of the GPS signal received by the portable electronic apparatus side GPS antenna and the GPS signal received by the in-vehicle electronic apparatus side GPS antenna, on the basis of a detection result of the detecting portion.
