To get rid of the vinyl residue use Mötsenböcker’s http://www.liftoffinc.com/product-tape-remover.php
They sell it at Home Depot or get it from Amazon. This stuff is amazing and will not mess up any finish. I have used it on fresh Lacquer and it only took off the adhesive. Saturate the adhesive and let it sit for a few minutes. Wipe off the dissolved gunk and repeat. It is slower than Goof-Off, but much, much safer.
Back to your original question, I would get rid of the Launch, and live with it for a few days. You can always take off more, but it would suck to put on the new stuff and find out you like the cleaner look.
