Same thing on my 04 and the dealer said it was a misadjusted yaw sensor that had to be reset electronically...being a dealer, still charged me $80 for the "inspection" to find the problem. ouch.

One question I am looking to help me with finishing up: does anyone know how to make the new head unit display to the OEM GPS screen as well as on the new head unit? Several YouTube professional installers show they did this, but I can't figure out the setting on the OEM controls to display the auxiliary video input signal from the new head unit, even though it is wired to do so. Thnaks!

I just replaced the OEM Mark Levinson head unit with the JVC KWNT800HDT 7-Inch DVD-CD-USB-SD HD Radio Navigation Receiver. Still a work in progress due to nagging finish and adjustment issues. I do not recommend using the JVC unit because there are several problems but maybe you maybe can avoid them with other unit. I am not a professional car guy but generally I can figure out work arounds when needed with cars and eletronics. First, you will need to get (in addition to the new Double DIN head unit) an adaptor kit; Beat Sonic is the only one I know of that is for specifically the SC430; it is Beat Sonic MVA-12L, for 2002-2004 models. It is expensive, $430, but it works as advertised, preserving steering wheel controls and OEM navigation unit, as well as the original speaker system. Second, there is a good set of instructions on line on how to remove the old unit, which is tricky and requires several steps in exact sequence. It only costs 5 bucks but has excellent pictures of the steps to avoid damaging anything trim or otherwise. Just search on Car Stereo Removal, LLC. Okay, the problems. Foremost, if you have white leather interior like we do, the reflection off the seats in daylight washes out the screen terribly, even on brightest setting. You have to turn off the feature that adjusts brightness at dark, because your daytime running lights makes the unit think it is dark and lightens the screen. Net result is having to manually adjust screen brightness after dark to keep if from being too bright, while keeping it at brightest setting in daylight. Might be able to bypass the daytime running lights, haven't had time to experiment with that, though. The trim kit that comes with Beat Sonic will not fill all the gaps from Double DIN unit. Still exploring options on this myself. While the wood door will come down to cover the new head unit, it must be in the inverse slant angle. to do so. Not all GPS head units have this motorized face place. This is another problem: the face plate must move up to open access to DVD/CD input slot, but on the JVC, it misses clearing the wood trim on the console cover by about 1/4 inch, so I have had to modify the plastic trim on the heated seats control module (everything fits together like a jigsaw puzzle on the console trim). Net result - trim cannot reseat in original retaining brackets and still get the GPS face plate to move up and down as is necessary. Third item: placement of the microphone for BT phone capability is a challenge. I put it down on the steering wheel column right below the wiper switch arm. It would be better if up higher, but you would have to disassemble the trim on the windshield column to do that - very hard to do. Net result, with convertible top down, the BT mike is barely satisfactory for conversations. There are several other issues, but please ask only if you are still intending to make the conversion.

Thanks for the help! Got warm enough today to get the project done without numbing extremities, for a change.

Does anyone know how to remove the old wiper blades? The SC430 hood prevents raising the wiper arm up to vertical in order to reach the detention pin on the wiper arm bracket and release the blade. Opening the hood gives some access, but the blade arm seems to move only about 4 inches away from the windshield before it stops. Has anyone performed the wiper replacement? Thank you!
