Where To Buy Lexus Is300/200 Original Gps

[GJA003]

Hey Guys new to forum

I've recently purchased a Lexus is200 as my first car.

Not the performance i was looking for but it fit the budget and looks the part.

Other then finding it slow through 1st and 2nd i found the sound system lacking todays standards,

the plan is to upgrade the sound system to something nice loud and clear no big sub's needed.

Also planning to lower it a fraction and find and original gps unit to fit.

So here i am been looking for a wrecker that may have the gps unit. Does anyone know if it will be a pain to fit ?

I've seen some guys put the common tomtom or navman gps where the factory screen is an i would be happy to even fit that ?

Just need opinions and ideas where to contact and such thanks.
