Hey so Im new to this site and also a newly owner of a 2001 Acura MDX. Long story short just got home last week from a 2 week vacation and while we were away my wifes friend was borrowing her 2000 Honda Accord and came home to it having a blown engine. Not happy as you can imagine. So i just bought this 2001 MDX in cash with 112,000 miles. So I have a PO740 code coming up from a check engine light. And also the radio is not working as well as the navigation. Radio has an err6 code and the navigation is saying disc error. Is this a big deal and what are my options?
