Sorry did not get back to you in time, I got several questions:
1. why eonon, I searched the web and found comments on its products are about half and half. Lots of people have quality problem (esp. on GPS).
2. can you give me a ballpark figure for the total cost of the upgrade?
3. where did you purchase the harness, any web site?
4. how long it took you to file off the extra part?
Thank you very much for your reply. HAGD.
