Fitting sat nav in a 2003 ram

From : yar

Q: has anyone else experienced the chronic warping of rotors that seems to come std. w/the 20 wheels on the 02 and newer rams i am wondering if anyone has had their problem truly fixed. i first experienced this problem w/ about 3000 miles on my 03. well the odometer just flipped 12000 and the problem is back. after the first trip to the dealer i had the rotors replaced and the problem seemed to be corrected. brake operation seemed normal no odd side effects. i just got the truck back from the dealer tonight and heres the latest fix which part of a tsb now - replaced both calipers in the front replaced front pads machined rotors after inspecting runout and thickenss. on the trip home i had to make a fast stop. i had to push the pedal what seems like halfway to the floor now to get the brakes to really engage. when they do engage they feel kind of spongy does this sound like the technician didnt bleed the brakes completly .
