Sequoia 2005 SR5 Antena Problem

[Sunny]

Hello

I got a Toyota Sequoia 2005 and replaced the standard JBL system with a Pioneer in dash Navigation unit. I now cannot catch any AM stations.

The local auto mechanic says that it is because Sequoia does not have external antenna and cannot catch AM station. However, the built in units uses 2 antenna inputs and the JBL systems are designed to use 2 Antenna inputs and work fine, however, the pioneer navigation unit just has one input option and anything other than the external Antena input leads to AM signal issue.

The antenna for Sequoia 2005 is built into the rear window glass on both sides and there is not external antenna.

Any ideas on how I can get an external antenna and fix it without drilling any hole in the body of the vehicle ?

Thanks
Sunny
