I picked up an IGO unit today. They had some of their older tips and they had newer tips in different packaging. According to their information in store (little product selector) and on their website they say the tip is a105. I saw the a69 tip and it looked exactly the same for $5 less (in old packaging) so I decided to buy it. I called their customer service while in the store to verify. They said the a69 is their older model and has been replaced with the a105. When I went to check out, the tip was only $5 canadian vs. the sticket price of $9.99 so in the end saved $10 off the a105 tip! I came here just to make sure I could use the a69 and I found this thread. Thanks!
