I purchased my Jeep Compass a few months ago and have the maxi care lifetime warranty. I am wanting to upgrade the sound system and Ive been trying to find out if doing so will void my warranty. I know it will void any warranty to do with the sound system but more concerned if something else goes wrong i.e. window wont roll down, will they try to link it to any changes I have done to then void the warranty? Ive contacted Jeep a few times but couldnt get an actual answer. Has anyone else dealt with this?
