Aftermarket Stereo With Factory Navigation

[BigBeau1231]

PLEASE HELP!!!

Hi guys , so i have recently picked up my first is200 1999 sport its in great condition and i love it but i do have an issue that i need some help with, the stereo/cd changer in it does not work and i would ideally like to replace it with an aftermarket double din stereo of some sort but i have read on here that there is a chance if i do this my navigation screen will stop working, please does anyone know a way around this issue as i really want to keep the navigation working along with a aftermarket stereo, im sure that people would have had this same issue plenty of times before so if anyone can guide me through this or tell me what i need it would be massively appreciated as at the mo i have no clue , seriously any help would be great !!! Thanx for your help guys ;)

You need one of these Rupert, just connects to the tx wires from old stereo, can help with wiring diagram if you need it.

You will lose voice guidance but still have working navigation btw

Ok i guess that doesn't really matter as its more for cosmetic purposes really , so do i use this along with the amp bypass lead yeah? Where exactly are the tx wires located and is it easy to connect? Thanx

Dont mean to sound stupid but first time doing this so

wanna make sure i get everything right ;)

[IHgs300]

Yes you use it with the amp bypass. The tx wires are located in original stereo plug.

red/white tx- and red/blue tx+

NEVER feel stupid asking questions, it's how we all learn mate, no-one knows everything.....
